My personal fix to a frame .stl I originally bought off cults3d for the PY2A website's rails. After I found issues with the original frame and rail design from the website. I realized that both frames have a major problem with the front rail missing a slot for the slide lock spring on the frame because the hole was designed too small to print on most printers and there was a gap where the recoil spring rod seats. I liked the compact design soo much. I decided to try and fix the problems by creating a part that simulates both missing components because of the cheap pressed sheet metal style rails. I did have to cut the rails to fit the compact frame. but in concept this part should also fit the original style frames from the website. Either way I included the frame I used with the new part. and a rmr plate just in case you dont have one. if you need further instructions on how to cut the rails to fit. let me know. ill post a youtube video or something.
