Prusa i3 Y IDLER Replacement Tensioner

Hi!

I broke my Y idler on prusa i3 (too much pressure on screws). As I did not wanted to completely unmount the Y axis to replace it, I designed a replacement one, also able to tension the belt.

I made 3 versions:

• Prusa I3 reworked
• Prusa I3 reworked 1.5
• Prusa I3 MK2

All need two M4 screws. The length depends on your belt and the tension you want to apply.

I include the 123d sources if you like the concept and need to adapt is to your printer.

Hope you like it.
