Y Axes Belt Tensioner

4020 profile tensioner.

Used on Tevo Tornado and Creality Cr10 (I used on a modified Ender 3)

I used the original 688z tensioner bearings from the ender 3.

Added a shorter version.

These are required for assembly:

5mm screw with nut.

4x20mm screw with nut.

2 T nuts (from original tensioner)
