This is the latest of my gantry plate design. This is inteneded to be compatible with the OpenBuilds gantry plate mounting points. This is for 2020 extrusion rails with 24mm wheels as commonly found in printer kits and the usual online sellers.
The 5 holes in the center are spaced 10mm apart and are for 5mm screws. The holes for the wheel axles are also intended for 5MM hardware. The top holes are 7.3mm and designed to fit eccentric nuts to allow for correct tension of the wheels to the 2020 rail.
The part is 60mm square and 6.35mm (1/4") thick.
