2020 Tensioner (Tronxy X3 X axis)

This is a simple but functional tensioner for the X axis on my printer. I use it on a Tronxy X3A, but can be used on other printers where the belt is running inside of the slot-profile.

It has to be mounted at the end of a 2020 profile.

I just realized the STL files are not in ideal printing orientation. You'll have to rotate the base, so it lays on its large flat back. Also the knob has to lay on its flat end.

You'll need:

1 hex screw M4x30
1 hex nut M4 (inside knob)
1 screw M3x20
