keymod rail

thingiverse

I created this as a replica of a rail I had, but I needed a larger hold to grip electrical accessories mounted on it securely. The two screw holes are slightly different from one of the keymod rails I own, but it fits perfectly on my gun. I'm not sure if keymods vary or not, but this works flawlessly on my airsoft replica. I printed at 15% infill and it seemed acceptable, but when I tightened the screws firmly, it caused the screw to break through the hole. When I printed at 100% infill, it gave it a nice weight and prevented me from tightening the screws too tight without issues. You can experiment with different infills. It was designed using Blender.
