Click-in fixed sander upgrade

Print in place clamp for my mobile workbench so I can sand with my orbital sander outside and avoid the dust inside. The set-up time is litterally 8 seconds. 

Print-in-place and crack every articulation once printed as if you were a chiropractor to open and close the clamp. Use no brim or raft. Printed with 50% infill.

3 STL files below and only one need support while printing. I created a version screwable with teardrop shaped holes (no support needed) to use with any workbench. This desgin is also good for storing the sander on the wall. 

Adapted to be sure that any rotating part of the sander would not touch the work bench and that no part of the dust collection or motor cooling are affected by the clamp.
