I created this model to simplify de-soldering Kalih hot-swappable sockets for MX-compatible keyboard switches. Idea being to place it under the PCB as if it was a switch, and then let gravity gently push the socket up from the PCB once you heat the pads and alternate between left and right.
Designed to fit the keyboard I was desoldering from. Has a cut out to fit a led, which can additionally help to align the jig. I assume it will generalize quite nicely except possibly the led - but do give it a try!
Outer dimensions: 14x14mm.
OpenSCAD file provided in case it doesn't fit your keyboard.
I've printed it in PLA which works but expect to run through a few copies if you heat so long that the plastic becomes deformed. No special settings required.

(In hindsight I should just have bought new sockets, but if you also get the idea of desoldering then this should aid.)
