So I've been thinking about which parts of an autococker could be replaced by 3d printing, allowing for endless customizability on a budget. Turns out the cocker has most of its pressurized parts fairly close together and I believe you could get away with a single lathe machined part and 3d print the remainder of the body.
We have seen pipe bodies before, but I believe they can be simplified even further.

This is probably gount to ruffle some feathers, but please let me know what you think especially regarding the safety aspect. Only piece I could see failing would be the firing valve, and it might be worth to move to a standard cocker valve with retaining nut instead of relying on the valve set screw that seats partially in plastic.

- Everything beyond the firing valve really doesn't need to be airtight, just close enough is fine, however to improve your seal and durability, you could make use of a second machined upper tube for the barrel threads and bolt o-ring contact surfaces.
- The entire body around the hammer doesn't need to be metal so the lower tube can be kept short which should drastically reduce material cost.
- The VASA can be moved to a mini-style front block, so all other operations on the tube can be performed on a lathe and a drillpress.
