Prusa Mini Tool Holder

Remixed from https://www.thingiverse.com/thing:4435739 I wanted a larger tool holder with space for my calipers. I redesigned the entire thing using OpenSCAD as a way to learn how to use it, changing the mounting system in the process; but I got the idea for the tool holder from there so they deserve credit.

At last print, I had to warm up the back piece with a lighter in order to get it to fit (near where the Z motor wires run down the extrusion). It was really tight given the angle it has to go on at, you kind of have to hinge it over the round screw part that sits on top of the extrusion at the front side of the printer. I've since moved the part called "back ledge" in by a couple of mm to allow a little more clearance that *should* get around this problem, but I haven't bothered to print it again as I managed to get the last print working well enough. If you do print it, please let me know how it works for you.

It sits on there really well at the moment and doesn't wobble o
