Clamp with elastic bands

This is an original model although I got the idea from seeing a free clamp model, laser cut out of three sheets of plywood and glued together. ( https://hobowithwood.com/ )

I thought the model was much more suited to being 3D printed. 

All the pieces just push into each other. the elastic bands keep the parts together. The top pincers swivel slightly and again just hold in place, so  no need for screws or other devices to pin everything together.

I tapered the sharp edges around the model so they would not cut into the elastic bands.

The parts have a 0.2mm designed gap, where movement takes place. 

The .stp model has all the parts joined together for printing, I wanted to print in situ and whilst it did work, I think the contact between surfaces will not work on every bodies printer. 

So you can either use the gcode provided where everything is exploded or in PrusaSlicer use the spit objects command and arrenge the model yourself. Support enforcer I set at 0 to ensure the PrusaSlicer did not support all the tapered edges.

PLA with 15% infill has worked for me.
