I designed these flexible bumpers to slide onto my kitchen cabinet handles yo prevent them from damaging my walls. Instead of stick-on dots that fall off or collect grime, these are permanent, adjustable, and custom-fit.
This model is fully parametric and written in OpenSCAD, so you can easily adapt it to your own cabinet hardware.
I've provided OpenSCAD and Fusion360 files with these adjustable parameters:
handleDiam – nominal rod diameter
handleClearance – fit adjustment (adds to hole diameter)
outerDiam – overall bumper diameter
wallThick – radial thickness of inner/outer rings
spokeCount – number of internal spokes
spokeThick – spoke thickness
totalThick – overall bumper thickness
