Ngàm/Insert cố định rail MGN9 cho BSB extrusion

I had an issue that I use BSB extrusion for building my printer with MGN9 rail. That extrusion has grooves that do not allow stable level mounting, so I designed an insert that can hold the rail straight. Step file included. I printed this with ABS with 0.2 layers 3 perimeter 5 top/bottom layers. Infill 20%. The brass inserts are standard voron M3 inserts.
