About this 3D model

To do the Bed level, I tried different options, but not with the expected results. So I decide to do this Support. It fits to any 20mm Aluminium Extruded profile face. Just add a couple of T nuts and M4 screws. The benefit is, that you can slide all over the extruded profile. Move the Bed over the Y axe as many times as needed with a gap of 3cm or 1 inch.
