Self-closing (unlevel) door stop

thingiverse

I'm including this simple tool to stop a poorly aligned door from auto-shutting itself. It functions by introducing friction into the door hinge. The original scad file is attached as this solution may be too specialized for my specific door hinge to be otherwise useful. Adjusting the inner and outer diameters should suffice. I installed one of these rings on each top/bottom hinge (between the stationary and moving parts, onto the door hinge spindle) and all auto-closing has ceased. Only time will tell if this solution is effective in the long term, but I can simply reprint them every few years if they start failing.
