overall great design for my 22 rounds. I printed in clear petg and blue petg, and green 90a tpu for the seal (only color I had laying around). will give a boost too for good design and overall printability. feedback is that the bolt holes need some work to achieve a more uniform finish. printing round holes is always a challenge in a vertical plane, although. I did end up getting a lot of stress cracking, so I added some super glue to hopefully hold them together longer. I think some hole reaming could potentially solve this issue, at the cost of threading. A great v2 idea I could suggest would be larger holes and move to longer bolts with a nut on the end.
