Useful little tool for removing 3cm pixel pucks, like the kind sold by Paul Zhang, from their mounting tracks.

The pucks attach to the track via 4 little clips, that you have to press in, while maintaining pressure to pop the puck out. They have the maddening tendency to slip and pop back up on one side.

Tested and used on a few dozen pucks, takes a little bit of finesse, but once you get the hang of it you can pop pucks out in a fraction of a second
