Clockwork2 Mounting Arm for PUG remix

I was very happy with cliftoce's PUG mount for CW2 but the heatsets were pulled out when I tightened the clamp.  Simple remix to move them to the back so they can't pull out.

Parts are oriented for printing with no supports needed@40% infill, 4 perimeters, 5 top/bottom layers.  Only the arm has changed, if you printed the clamp from the original you can use that.

Moved the heatset inserts to the back so they can't be pulled out.
