Made a cradle for the Milwaukee m12 rotary tool. can hold the tool alone or with an attachment and 1.5 AH battery on it. Made it so the tool shouldn't slide or shift out of place and get banged around.

Its a rather large print, so you may need to cut it in your slicer and do it in two parts.

Feel free to remix/optimize or do whatever to it, since I'm not that great at modeling in freeCAD. you could probably make a shorter version if you don't care about overhanging into other grid slots or having to take everything off the tool.
