how to assemble the gearbox:

I hope to see a lot of your Makes!

This is a gearbox for various motors. I designed the gearbox to test how durable 3D printed gears are. So the test is a part of a bigger project that I am working on. Maybe someone will find this project usefull. It's Easy to print and assemble and the gearbox runs really good.
The gearbox has a reduction of about 1:6.5. This gives you a higher torque
- 1. gearstage 15 to 35 teeths --> ratio of 2.33
- 2. gearstage 15 to 42 teeths --> ratio of 2.80

==> ==> You coud use it with DC or Brushless motors with a mount diagonal of 19mm or 16mm or you could add other holes.


I hope to see a lot of your Makes!
