This is a remix of a tool found on Thingiverse (https://www.thingiverse.com/thing:2775085) I added more support to stop the prongs from breaking on the first use. I have one that has opened about 200 switches that still works. Going, to be honest, I bought a metal switch opener that works a bit better. But this is still good to use and is much cheaper.
Would suggest you print in PETG or stronger filament with a resolution of 0.15 and infill of 20%.
