Hi there, nice design. For cheap chinese BMG clones you might need 3 pcs m3 x 40mm screws as the ones delivered with the extruder are too short when using this mount. Keep up the good work. :)

Seems rock solid. Why one the the 4 stepper screw hole is wider that the others (top right in the picture) ?
Thank you

The Bondtech BMG only has 3 through holes for mounting, the larger hole is recessed to install a shorter screw to attach the bracket to the stepper.

I had an issue with this bracket, the motor was too close to the extrusion mount and it would not line up. I made one in Tinkercad that used a different 2020 mount (https://www.thingiverse.com/thing:2519252/files) and the motor bracket from a Bondtech stl (https://www.bondtech.se/en/customer-service/printable-stl-files/).
