This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/3KgXbDUkTnb
This has been modded form the KNRLR to fit 6mm bolts, also cut of corner to give more room for m3 screw.
I have put the parts together on one table apart from dremel attachment that's in a separate file,which is a copy of the one from the original KNRLR
I have printed and looks ok, see picture
