Gearbox powered Flying-Toy (1:32 gear ratio; mostly printed only)

UPDATE:

• uploaded an improved rotor with much better flying performance and easier to print (printed it with 0.2mm layer height and tree support)

**Important Notes:

• i do not recommend this for 3D print beginners
• you have to use silicone spray to make the gearbox work properly
• i have not done long term testing - so far it works like a charm
• all gears should be printed with 0.1mm layer hight and the teeth have to be 100% clean
• during assembly, make sure that every single gear can rotate without any resistance
• to make the gears rotate easily, rotate them 2-3 times, deassemble them and clean the touching surfaces - repeat until no more resistance is noticeable
• see .stl info field for quantities
• you'll need 5x cylinderhead screws M3x8mm + 4x M3 nuts (make sure, no screw will block any adjacent part)

I've printed all the gears with 0.1mm layer height PLA 200°/60° and normal support.

All casing parts and the drive_knob are printed with 0.2mm layer height.

For the rotor i had best results with printing 0.1mm layer height and tree support.

I'm still working on improving the rotor and will upload further variants later.

See pictures for printing orientation.
