Modeled this to fit a 5KU Zenitco PT-1 replica stock to my CYMA airsoft AK. I've included a 'flat' version with no angle correction and a modified version with angle correction for CYMA AKs so the stock will actually be 'straight' when it's open instead of sitting at a slight angle.
The latch-catch on this was designed to be tight so there's as little wobble as possible - minor fitment may be needed if it's to tight for your gun at first (small file or a pocket knife will be all that's needed).
I'd suggest PLA w/ 1.2mm thick walls and 75% infill as this is what I've tested and can vouch for.
I've confirmed this adapter fits CYMA CM058 and CM031C - if you are able to test is on other models / makes please let us know!
