I have been looking for a mounting plate for a Titan kit with mounting bracket, but have not found it. So I made the mount from the BMG extruder to fit.
Fits original MDD plates, but also clones like https://www.amazon.de/gp/product/B08N5JFKQS.
For a tight fit, set the scale to 99% and select min. 2.4 mm wall thickness at 50% infill. Pull 2 pieces of insert nuts in 5 mm distance with a long M3 screw from behind through the mount to be able to fix it securely to the MDD. So neither a soldering iron nor glue is necessary ;)
