Printrbot Y-belt end with flower nut.

A remix of my alternate y-bar end.
The original is still working perfectly after almost 2 years but I'm raising the bed and need to go back to the original belt clearance - 15.5mm from bed to belt edge.
Sketchup file is included if you need to modify the height.

Later.
Now after installing them they are a little bit too long.
11.5mm version added.
