This is a simple modification to the original OEM Elegoo Centauri Carbon "CC MINI" model.

The original "CC MINI" model is available from Elegoos website and from the USB stick that comes with the printer. It comes with two 3mm screw holes, since it is intended to be mounted at the back under the filament purge (poop) chute.

You can use this modded version anywhere on the sides of the Elegoo printer where you have a single spare 3mm case-screw hole. I use it as a storage container for holding snips, tweezers, files, a torch, and other printing tools and materials. The single case screw is plenty strong enough.

There are two variants:

1. Standard variant
   This has no special print requirements. No brims required.

2. Magnetic variant
   Though the single screw holds quite well, if you'd like more stability, the optional 'magnet' variant is designed to take two Ø 6mm x 2mm round magnets. The holes have been given 0.025mm diameter tolerance and are also 0.078mm recessed so you could use a little glue and the magnets shouldn't scratch the panel. If using PLA, being a bit softer, you could add an X-Y hole compensation in your slicer (e.g. 0.05mm).

Feel free to mix your own and enjoy!
