Printing settings
Most parts can be printed with 3 walls and lightning infill, except where noted below.
Colors (as in the reference image):
Black:
- Case.3mf (Use 5% grid infill for better stability).
- Screw.3mf
Red:
- Hook.3mf
- Pointer.3mf
Silver:
- Cover.3mf
Random Colors (Internal Parts):
These are not visible, so color doesn’t matter. High-quality filament is recommended.
- CenterGear.3mf
- CentralPin.3mf
- Connector.3mf
- GearBase.3mf
- Lever.3mf
- OuterGear.3mf (Use 80% grid infill as this serves as the counterweight).
- PlanetGear.3mf
Multicolor Panels:
Panels can be printed on a standard single extruder printer with manual filament changes at specific heights. Use 0.1mm layer height for best results.
Pannel-MPH.3mf and Pannel-KMH.3mf:
Start with black and switch to white at 1.2mm.
Pannel-RPM.3mf:
Start with black, switch to white at 1.2mm, and to red at 1.8mm.

Assembly Tips
- Friction is the main challenge. Ensure all parts are smooth and free of strings. A heat gun or torch can help remove imperfections.
- During assembly, test each moving part. If anything sticks, consider sanding or identifying where it’s catching.
- While the OuterGear works best with 80% infill for weight, tests show it can function with lower infill if the system is smooth enough.
