21 teeth pinion

thingiverse

I designed and built this custom pinion for my Tamiya Dirt Thrasher after the original aluminum one wore out due to excessive wear from its 540 type motor. It performed quite well, but I'd recommend easing up on the throttle to prevent further stress on the new part. Print Settings: Printer Brand: Prusa Printer Model: Prusa Clone Raft Support: Not used Support Material: None required Layer Height: 0.25 mm for maximum precision Infill Percentage: A solid 100% for optimal strength and durability Notes: The pinion fits snugly onto the motor shaft, requiring a moderate amount of force to secure it in place.
