This is a parametric door handle bumper inspired by kulfsson's Door handle bumper

I have a rectangular door handle so I created this version to allow for rectangular and circular holes. It's not as smooth/curvy as the original, but it works well.

When I measured the door handle I rounded down, cutting off about 0.5mm for a snug fit.

Things that can be customized:

• Shape of each hole (rectangular, circular)
• X and Y dimensions of each hole
• Thickness of the wall of each hole
• Distance between the two holes
• Height
