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 an OpenSCAD file 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

I mainly made this so I could learn how the model customizer works.
