Remix of https://www.youmagine.com/designs/keycap-puller . I did it because the original design was a little big for using on my HHKB (topre), I think this remix does a better job on this kind of keycaps. Thanks to the original designer.Tested using PLA, layer height 0.2mm , extrusion width 0.4mm.
UPDATE: * version 2 is wider to be stronger.
