This is one of the many paintball projects I tend to pick up. It’s a cylinder for a paintball revolver that was made in the ’80s (Crossman 3357) which like many markers of that era has a small cult following now.
The problem with these cylinders is that they’re plastic but they’re located with a metal pin. So the plastic teeth get worn out and the whole part needs to be replaced.
I priced out a bunch of different options for the customer, ranging from what we did (FFF printed PLA) up to SLS stainless steel. I modified the original design to use individual o-rings to hold the round in each chamber, so that the customer can use the smaller paint that tends to be available now. Waiting to see how it performs when he has it installed.
