Adjustable Y-Tensioner for Bear

While my other y-belt tensioner works OK I didn't like that the adjustment screw is still so hard to reach.

This is a very simple design. The back plate is screwed to the extrusion and two screws stick out for tensioning. The other is just for guidance. It's only slightly bigger than the original Bear idler.

Needs:

• 2x M3x20mm hex
• 1x M3x10/12mm hex
• 2x M3 loc nuts
• 1x M3 (loc) nut
• 1x M3x20mm cap
