i3 2020 Y Axis Tensioner

This is a Y Axis tensioner for the belt on a i3 2020. Has worked great for me and it's been in use for several months now.

I re-used the bearings for the belt side. I shifted the old T-Nuts to the side so I could use them to hold the base in place. Then I used a M3x30 Screw and a M3 Nut to tighten / loosen the belt.
