Minimalist Dual Z Axis Belt Tensioner

Do you have a dual z axis on your printer that needs a tensioner? Did you upgrade your tensioner and still have the old one laying around? 

This is a minimalist dual Z axis belt tensioner that uses an Ender 3v2 tensioner pulley. You'll also need (2) m3 T nuts, (2) m3 screws, and an m4 nut.

Use your imagination to adjust the belt tension by moving the tensioner closer or further away from the Z axis. Put it in different position, flip it backwards, etc.
