Quick release dumbbell clamp

###Quick release dumbbell clamp

Designed for the common 25mm diameter dumbbell bar.
Prints in place, supports required for one of the arms (I used paint on supports - blue in the slicer screenshot). The hinge surfaces will most likely stick, use a hobby knife to cut/pry them apart being carefull not to cut too deep. I have also added modifier cylinders in the slicer to increase the infill density of the hinges (pink in the slicer screenshot).

Slicer settings I used:
* 0.2 mm layer height
* 0.5 mm nozzle width
* 31% infill, 75% on the modifier cylinders
* Suports for suport enforcers only
* 3 perimeters
* 4 solid top layers
* 3 solid bottom layers
