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

**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 - 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. Quantities for Gears: Gear1: x1 Gear2: x1 Gear3: x2 Gear4: x1 Gear5: x1 See pictures for printing orientation.
