KAM Snap Press Die

This thing is a replacement die for your KAM snap riveting tool. The original tend to split after a while and since it's plastic, a new one can easily be printed.

Use a hard filament. I initially tried ABS and it didn't work; the snap formed a divot in the die after a number of cycles. I printed it in polycarbonate and that seems to work. Annealed PLA might work too.
