I ReMixed from this thing https://www.thingiverse.com/thing:1721927 Firstly, increase the size by up to 10% in your slicer, depending on how good your settings are, as I found the MT2 to be tight when inserting it into the handle. This design is intended for an MT2 ER20 collet chuck and I hope it will prove useful.
