Hands Free Round Door Knob opener

pinshape

Modified design from @adapta Adaptaio uploaded at My Mini Factory I modified design to allow for adjustable squeeze latch handle securing to door knob rather than the zip tie style. I printed with Clear ABS on a Zortrax M200 at 90% fil and 0.09 mm layers but can be up to 0.29 mm layers with a little clean-up work on smaller features.  Support was added at 35% or more angle, but the only place this happens is for the bolt holes.
