BentoBox base w/magnets and magnetic wire guide for Elegoo Centauri Carbon

A very quick remix of the BentoBox base w/magnets and an additional magnetic wire guide for use in the Elegoo Centauri Carbon (though both will likely work on other printers). Uses the same magnets as the BentoBox itself (since you likely have a ton left over anyway after the build).  There's a cutout on the bottom back edge to fit over the small ledge around the bottom of the printer and magnet mounts on the top and side to help hold it steady. The magnetic wire guide is a simple fixture to keep the wires from the Bentobox flush up against the side of the printer and prevent any chance at entanglement. Uses 22 of the small magnets total (12 on the base, ten on the wireguide), though you could probably get away with a lot less.
