Hands Free Round Door Knob opener

pinshape

I modified the design from @adapta Adaptaio uploaded at My Mini Factory. I updated the design to allow for an adjustable squeeze latch handle securing directly to a door knob rather than using a zip tie style. I printed the model with Clear ABS on a Zortrax M200 3D printer, using 90% infill and 0.09 mm layer thickness. However, it can be printed at up to 0.29 mm layers with some extra clean-up work on smaller details. Support material was added at an angle of 35% or more, which is only necessary for the bolt holes.
