Parametric TPU Bumper

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
