About this 3D model

Picatinny rails are not all the same - some are a tiny bit bigger, some are just a tiny bit smaller. I designed this re-sizable mount that could be printed as one model, but still can move. In order to secure it properly, use M4 screw (about 38 mm in length) and an M4 nut. It is just the attaching mechanism, so feel free to add anything you want to it. I am uploading the STP file and the IPT (Autodesk Inventor) file. Happy Shooting!.
