This is a replacement pin for Williams strike master. It should fit any other bowler that uses a 10 1/4" pin. I found these were slightly heavier than the originals, so I shortened the up spring by 3-4 loops and it works perfectly.

I used this file as a base to design, but thingiverse isn't allowing me to add a remix right now.

You will need a tall printer to print these as it's taller than 250mm. The game is currently on location and the pins are holding up really well.
