Ender 3 Tool Holder

This is a remix of 3324620 - just setup to fit the Ender 3 standard PSU (not the meanwell one).

Noticed a few issues with the initial upload - mainly on the blade holder and that I'd missed the nozzle holder spaces when I added objects in Tinkercad (as they were face down!).

I printed this without supports and it was pretty good - there was some stringing around the clipper holder which I just trimmed to make neat - print with support if you want to avoid this (which snaps off pretty easily - don't forget to paint the allen key holders to not include supports though).

Update in 0.7 - didn't fit on standard Ender 3 printers properly - it was fouling the Z axis roller. I've re-designed it, and you can now attach it to the PSU using 2x M4 screws into the holes on the back of the PSU.

I also found organic supports to work best when printing.
