V-Slot Rail Insert

This insert is designed to fit perfectly inside a V-slot rail, like those used in Ender 3, for an example. The insert won't interfere with rollers. The insert can be customized to for an example, mount LED strips or cables inside the rails of your 3D printer. You can edit the insert to fit your application. The wider surface of the insert faces outwards from the rail, and the narrow surface faces inside the rail. No scaling should be required, it should fit pretty snugly. If you want a tighter fit, scale the whole part up a bit.
