Airsoft SAS Front Kit

I made a SAS front kit for g type 18c and 17 airsoft pistols. I found someone talking about making one on the airsoft group and thought how easy it'd be. I tested the design on a stark g18c, it should have a tight fit. The file with the C at the end is a compatible version with the CYMA CM 030 since it has a longer barrel and other brands that have a barrel thats too long to fit the other versions. The long files have the under rail extended out, the full version doesn't have the gap in the middle of the rail and the short doesn't have the rail extended. The thread adapter is 14 mm negative on both sides. I printed using ABS, 0.2 mm layer height, 2 shells, 225 C, 10% infill and supports enabled.
