Y axis tensioner

Y axis tensioner for Ender 3 pro. You can use this design to properly tension your belt for Y axis. The middle part, can be changed for different pulleys/bearings and also adjusted in left/right direction if the belt is binding one of the sides. The right allignment of the belt can decrease vertical artifacts on the print.

Mounting/Printing tips

• Full_Body.stl print vertical, without supports
• Inside.stl - print flat

Inside_+/-1mm can be used to better adjust positiong of the belt, so there is no binding. You can use this model to prepare your own version.

Additional parts:

• M4 20mm screws - 2x

Version 2

In this version you can easily swap different "Inside" element (each can have different pulley, bearing, offset) without full disassembly. Just slide it off :)
