I have now built a more stable landing gear based on this landing gear https://www.thingiverse.com/thing:865739. It's a repair landing gear that has the engine screws attached.
Pressure Notes:
- Left and right leg without support
- Rear frame with support and brim as pressure plate
- I would print it with ABS, but should also be printable with other materials
The files:
seen from behind right: leg right.stl
seen from behind left: leg left.stl
Rear rack: leg back.stl
