This model is easy to print and easy to assemble without any glue or additional parts. The chosen tolerances hold the model in place.
If you are arranging the parts with the slicer software place them in the same orientation as in the second picture.
For most of the parts I used a layer thickness of 0.2mm. For the worm and the worm wheel I used 0.1mm and activated supports (don't forget to remove all of it after printing).
I used PLA filament.
The author marked this model as their own original creation.
