Anyone printing parts for RC planes, drones, or cars knows the printer itself is only half the story. The real difference shows up in the spares you keep on hand: a fresh extruder gear when feeding gets gritty, clean Bowden tubing, a hotend ready to swap, and tools that make cleanup fast instead of frustrating. This list gathers ten accessories that keep a hobby workshop running smoothly, from filament built specifically for airframes to bearing assortments for custom wheel and gear designs. Each pick suits a different stage of the hobby, whether your first print is still curing or your hangar shelf already sags with spare fuselages.

More Details On Our Top Picks
An extruder gear is the toothed brass wheel that grips filament and pushes it toward the hotend, and it wears down faster than almost any other moving part. Ten of these 40-tooth wheels cost about as much as one failed print session’s worth of filament, which makes them cheap insurance.
The teeth mesh with Creality’s standard drive setup, so swapping one onto an Ender 3 or CR-10 takes minutes with basic hex keys. Hobbyists printing flexible TPU for tires and landing gear tend to chew through gears quicker, since soft material demands more grip pressure.
Strong Points
- Ten pieces mean a worn gear never grounds your printer mid-build season
- Brass construction resists corrosion better than plain steel alternatives
- Fits most standard Bowden extruders beyond the Ender line
- Restores consistent feeding once teeth wear flat and start slipping
Things To Consider
- You’ll want to verify tooth pitch matches your current gear before ordering
- Set screw alignment matters; a crooked install causes wobble and uneven extrusion
Who Should Grab It
Ender and CR-10 owners who print often and want spares on the shelf before a failure strands them.
Where A Sibling Pick Shines
Shoppers wanting broader maintenance coverage should look at the Creativity Full Assembled Ender 3 Hotend Kit, which replaces the whole hot side rather than one gear.
Most first-time printer owners discover the hard way that prints don’t pop off beds by themselves. This 34-piece set from Intarsio covers the removal, trimming, and nozzle-cleaning basics without burying you in duplicates, and it works across both FDM and resin-style SLA machines.
The selection leans practical: two MK8 brass nozzles, five cleaning needles, a steel scraper paired with a razor spatula and spare blades, five file shapes, brushes, wire cutters, and an engraving knife. For someone clearing support material off a printed wing saddle at the kitchen table, that’s genuinely everything needed.
What We Like
- Spare nozzles save a print day when the stock one clogs permanently
- Razor spatula lifts stubborn parts without gouging build plates
- Five needle files handle seam smoothing on small RC fittings
- Works for resin prints too, not just filament machines
Minor Gripes
- Razor blades demand careful storage around kids or pets
- No carrying case, so pieces tend to scatter through a drawer
Made For
Beginners setting up their first printer who want one affordable purchase covering daily upkeep.
Another Choice May Suit
Hobbyists needing drill bits and pliers for heavier modification work will get more mileage from the Intarsio 68Pcs kit with its storage case.
Bowden tubing is the PTFE guide tube that routes filament from the extruder to the hotend, and degraded tubing is behind a surprising share of under-extrusion complaints. Old tube softens near the hot side, kinks, and adds friction that starves prints of plastic.
This Aokin bundle includes two 1.5-meter lengths of blue 2mm-inner/4mm-outer PTFE, plus four PC4-M6 and four PC4-M10 pneumatic fittings, the threaded couplers that lock the tube into the extruder and heater block. Two full tubes give you a fresh run now and a backup later, which matters because repeated re-seating deforms tube ends over time.
Highlights
- Self-lubricating PTFE keeps filament travel friction low
- Handles hot-end temperatures without melting or off-gassing odors
- Eight fittings cover both ends of multiple re-tubing jobs
- Suits Ender 3, Ender 5, and CR-10 family printers directly
Softer Spots
- Cutting tube ends perfectly square takes patience; angled cuts leak
- Blue color won’t match every machine’s original hardware
At A Glance
Right Fit For
Owners of Bowden-fed Creality machines noticing stringing, clicking extruders, or inconsistent flow after a year or two of use.
Swap It Out When
Direct-drive printer users skip this entirely and would benefit more from the Mudder extruder gear pack instead.
Where the smaller Intarsio kit stops at finishing basics, this 68-piece version pushes into actual fabrication territory. The headline addition is a hand drill with ten bits, which opens up drilling servo mounts, cooling holes in motor pods, and lightening passages in structural parts without borrowing the household drill.
Needle-nose pliers, a deburring tool, metal files, scrapers, tweezers, and cutters round out the loadout, all packed in a lidded case that lives neatly beside the printer. Anyone converting printed brackets into working RC components will reach for this kit weekly rather than occasionally.
Upsides
- Hand drill with ten bit sizes handles precision holes in PLA and PETG
- Deburring tool cleans layer edges on functional parts quickly
- Lidded case keeps sixty-plus pieces from migrating around the bench
- Pliers and cutters trim filament and bend small wire links
- Suits Bambu Lab, Ender, and Kobra machines alike
Points To Note
- Case bulk eats more shelf space than a simple pouch
- Drill bits are fine-gauge; heavy torque can snap the smallest sizes
- More pieces means more to keep organized long term
Who Will Love This
Intermediate hobbyists who modify, drill, and finish their own RC parts rather than printing and gluing as-is.
Not Your Match When
Minimalists who only remove prints and swap nozzles are better served by the leaner Intarsio 34-piece kit.
This is the kit to consider when the printer itself came as a box of parts. Creality packs 74 pieces aimed at the full lifecycle: assembling the frame, tensioning belts, cutting filament, scraping the bed, and chamfering finished edges. Because it comes from the same company that builds the printers, the wrenches and drivers match Creality hardware sizing out of the box.
The wrap-style roll layout spreads tools flat for quick identification, a format some people prefer over digging through a case. Compared with the Intarsio 68-piece set reviewed earlier, this one trades the hand drill for stronger assembly coverage, so the right choice depends on whether you build or modify more often.
Bright Spots
- Driver and wrench selection aligns with Creality printer fasteners
- Chamfer and machining tools refine edges on visible parts
- Roll format lays every piece out where you can see it
- 74 pieces span assembly, removal, cleaning, and finishing stages
Small Caveats
- Roll storage needs a flat drawer or wall hook to stay tidy
- Users of non-Creality brands may find some drivers redundant

Whose Shelf It Belongs On
Builders assembling a new Ender or upgrading a secondhand machine who want brand-matched tools in one purchase.
Reach For A Different Pick When
Flyers focused purely on post-print part prep will find the Lankki 24-piece finishing set more targeted.
A hotend is the heated assembly that melts filament, and it’s the component most likely to fail dramatically mid-print. This Creativity unit arrives fully assembled, meaning the heater cartridge, thermistor, fan, and nozzle come pre-built and pre-wired, so recovery from a burnt-out hotend becomes a fifteen-minute swap instead of an evening of disassembly.
The stainless steel heat break and seamless nozzle-to-tube junction aim to prevent the molten leaks that plague tired stock units. For RC work, where a failed print can waste a whole evening reserved for the workshop, keeping one of these boxed as a spare is a sensible habit.
Reasons To Buy
- Pre-assembled design eliminates fiddly hot-side wiring work
- 24V high-speed fan pulls heat away efficiently for cleaner retractions
- Sealed nozzle and tube connection reduces leak-driven clogs
- Stainless steel components tolerate sustained high temperatures
- Drops straight onto Ender 3, 3S, and 3 Pro mounts
Trade Offs
- Only fits Creality-style mounts, so check your model first
- Stock-fan noise level may be noticeable in quiet rooms

Best Suited To
Ender 3 family owners who print regularly and want a known-good spare ready before disaster strikes.
Consider Something Else When
Your printer feeds fine but skips clicks point to the drive side, where the Mudder extruder gear pack solves the problem for less.
Ball bearings are sealed steel rings that let shafts spin freely, and they’re the difference between a printed wheel that rolls and one that grinds. Designing a rotating part around a standard bearing size beats trying to print a bearing itself, which rarely survives contact with a real drivetrain.
Dianrui boxes six deep-groove sizes together, from tiny 3x8mm 693ZZ units up to chunky 7x22mm 627ZZ bearings, twelve of most sizes and ten of the largest two. The labeled compartments make grabbing the right ring mid-design painless, and carbon steel construction suits light-duty RC applications like tail wheels, idler pulleys, and camera gimbal joints.
Plus Points
- Six sizes cover nearly every small RC rotation point
- Divided box prevents size mix-ups during builds
- Shielded ZZ design keeps dust out of the race
- Spares on hand mean a crushed bearing never ends a flying day
Worth Noting
- Carbon steel rusts faster than stainless in humid storage
- Light-duty rating limits use in high-load drivetrains

The Right Fit
Designers printing custom wheels, pulleys, and linkages who want standard bearing options ready before slicing a new part.
Look Elsewhere When
Shoppers after airframe weight savings belong with the SainSmart LW-PLA filament further down this list.
Weight is the enemy of flight, and ordinary PLA at roughly 1.2 g/cm³ makes heavy wings. This filament uses active foaming technology: at higher nozzle temperatures the plastic expands inside the nozzle, producing parts around 0.54 g/cm³, less than half the density of standard material. Lower wing loading follows, along with gentler stall behavior on slow flyers.
The honest catch is tuning. Foaming responds to temperature and flow settings, so expect a few calibration cubes before your first wing panel comes out right. Once dialed in, though, builders commonly report fuselages and wing skins that feel startlingly light in the hand compared with standard PLA equivalents.
Standout Traits
- Foamed parts weigh roughly half what regular PLA produces
- Lower wing loads translate to slower, more forgiving stall speeds
- Active foaming lets you tune density per part via temperature
- Also suits drone shells and lightweight cosplay armor
Honest Caveats
- Requires temperature and flow experimentation before good results appear
- Foamed surfaces show more texture than glossy standard PLA
- Store spooled and dry; moisture degrades foaming consistency
Feature Snapshot
Who It Suits Best
RC plane and drone builders chasing flight performance who are willing to spend an afternoon dialing in profiles.
Skip It When
Structural ground-vehicle parts need stiffness and impact strength, where standard PLA or PETG serves better than foamed material.
Finishing is where printed RC parts go from obviously homemade to genuinely presentable, and this compact Lankki set focuses squarely on that stage. Rather than padding the count with duplicates, it curates 24 purposeful pieces centered on cleaning and refining.
The brush trio is the standout detail: brass for scrubbing unfinished metal parts, nylon for delicate finished surfaces, and stainless steel for stripping stray filament off nozzles. Add five diamond-profile needle files, a putty knife scraper, tweezers, and nozzle cleaning needles, and you’ve got the post-print workflow covered without drawer clutter.
Positives
- Three brush materials match the right aggressiveness to each surface
- Diamond files reshape hinge pockets and control-surface gaps precisely
- Putty knife lifts prints without marring PEI-style beds
- Small footprint suits crowded shared workspaces
Areas To Watch
- No storage pouch included, unlike the Intarsio 68-piece case
- Skips assembly tools entirely, so it complements rather than replaces bigger kits
Built With In Mind
Hobbyists who already own assembly tools and want a dedicated, quality finishing set for visible parts like cowls and canopies.
A Better Fit Elsewhere
Complete beginners starting from zero should step up to the Creality 74-piece wrap kit for full coverage.
Clogged nozzles cause more abandoned prints than any other single fault, and thin cleaning needles are the fix. Where most kits include three or five needles, this EILKBLA set ships ten 0.4mm cleaners, enough that losing one in a bench drawer barely registers.
Around those needles sit the usual suspects: steel and plastic scrapers with eleven spare razor blades, five files, two brushes, wire cutters, a craft knife with six blades, a wrench, and a tweezer. It lands between the minimal Lankki set and the larger Intarsio kits in scope, leaning toward nozzle care and part removal.
Best Bits
- Ten cleaning needles outlast frequent cold-pull routines
- Eleven spare scraper blades stretch the kit’s usable life considerably
- Craft knife trims brims and skirts cleanly off small parts
- Covers both hotend maintenance and bed removal in one buy
Room For Improvement
- Loose pieces arrive without organized storage
- Razor blades warrant locked-away storage in family homes
Right Fit For
Budget-conscious owners of a single printer who mostly need reliable nozzle unclogging and print removal tools.
Swap It Out When
Multi-material shops juggling several machines gain more from the Creality 74-piece kit’s broader driver selection.
What Matters Most Before Choosing 3d Printers For Rc Parts
Match Accessories To Your Actual Failure Points
Every printer develops habits. Clicking extruders usually trace back to a worn drive gear, while stringy prints often point at tired Bowden tubing. Before buying anything, note which symptom annoys you most and spend there first. A shelf full of unused tools helps nobody.
Weight Versus Strength Decides Filament Choice
Flying parts live by different rules than chassis parts. Airframes reward low-density foaming filaments even at the cost of surface finish, while drivetrain components need dense, stiff material. Decide which category dominates your printing before stocking up.
Kits Beat Single Tools For Newcomers
Buying tools individually seems cheaper until the third separate order arrives. Bundled kits also guarantee compatible sizes, particularly for nozzle needles matched to 0.4mm openings. Established hobbyists with a filled toolbox can cherry-pick singles instead.
Storage Shapes Long-Term Satisfaction
Sixty loose pieces become forty lost pieces within months. Cased kits such as the Intarsio 68-piece set hold their value simply by keeping everything findable, which matters more than raw piece counts over a year of ownership.
Key Considerations Across These Picks
Traps First Timers Fall Into
The classic error is buying a giant kit before owning the printer long enough to know your needs. Another is skipping compatibility checks; a hotend for an Ender 3 Pro won’t bolt onto every machine. Verify connector types and mount patterns against your specific model before checkout.
The Case For Spending Up
Higher-tier kits earn their price through organization and specialization. A cased 68-piece set costs more upfront yet saves replacing lost pieces repeatedly. Likewise, specialty filament like LW-PLA carries a premium that translates directly into flight performance standard plastics can’t offer.
Frequently Asked Questions
Can a standard desktop printer really make usable RC parts?
Yes, modern FDM printers produce servos mounts, wheel hubs, and even entire foam-class airframes. Part success depends more on filament choice and orientation than on printer brand.
Why does my extruder click and skip during prints?
A worn drive gear slipping on filament is the most common cause, followed by clogged nozzles and degraded Bowden tubing. Replacing the gear or tubing typically resolves it.
How often should Bowden tubing be replaced?
Heavy users commonly refresh it yearly, or sooner when under-extrusion appears. Heat exposure near the hotend gradually deforms the tube’s inner bore.
Is lightweight PLA strong enough for crash-prone planes?
Foamed PLA sacrifices some rigidity for weight, so designers reinforce high-stress points with geometry rather than material density. Many club pilots fly foamed-PLA airframes successfully.
Do I need special tools for resin printers?
Most finishing tools here, like scrapers and files, work on cured resin parts too. Resin handling does add gloves and proper ventilation requirements beyond these kits’ scope.
Bottom Line
Building a reliable RC printing setup comes down to covering your weak points first: a spare hotend and extruder gears prevent downtime, fresh tubing restores flow, and the right filament decides whether your next plane flies or flops. Start with the item matching your current frustration, then expand as the hobby grows. Your hangar will thank you, one successful print at a time.
