Fit great! I printed 5 and just scaled the height in the slicer from 0.2mm to 1.0mm. 0.8 mm was the winner in my case.

Printed mine with PETG and it turned out great.

However on my keyboard (Lily58) the OLED socket is in the way, so it is not possible to slip the one side of the puller under the Pro Micro PCB. Also, if you are using normal DIL IC sockets instead of two separate single line sockets, it won't work as well. See the photos. Not the fault of the puller, though. (edited)

Worked like a charm and easy to print! Great design, thanks a lot for posting it.

I had to replace a leaky bolt for my toilet tank and discovered it was leaking because the screw was slightly angled because the flush valve -- held onto the tank by a big plastic nut -- was in the way. I didn't have a wrench that would fit, but I suspected someone might have printed one... and after a few hours of printing and no costly trip to Home Depot, my problem was solved!
