Bumper key cap

My window's key is exactly at the same height of a light fixture, so if I open the window too fast, I risk scratching or even smashing it. I designed this keycap with onshape that has a spring that can be compressed or bent. The printed version has a spacing between coils of 1.5 mm, but that's a bit tight, so the uploaded STL has a 2mm spacing instead. In any case it's easy to create a branch from the model and change the spacing in the variables table. I printed using ABS (for a bit more springiness) using default 0.2mm resolution.
