Axis Tensioner - Y axis

Getting the Y axis belt tight enough can be a real pain. That's why I've designed this printable upgrade to allow increasing the tension on the Y axis belt / pulley by turning a screw.

You can find my X axis belt tensioner here thingiverse.com/thing:1673

V1 - Based upon a single captive nut.
V2 - Fixing an alignment issue.
V3 - First printable version. The smaller piece that holds the captive nut was too long.

V6 - Same concept, but a different design using two captive nuts on each side of the Y axis pulley. My test print is suffering from some X stage problem, so the prints aren't coming out right yet. However, I wanted to post this in case I could get feedback from others.

V7 - Same concept with a few improvements.

I created the screenshot from Unrepentantgeek\'s Sketchup version of the Cupcake CNC. thingiverse.com/thing:1449
