I couldn't find an enclosure for my RUMBA - So this was made to house the RUMBA controller board for my new custom CoreXY printer/CNC mill/laser with a 3-color diamond hotend. It is the same height as my power supply and has mounts for 2 60mm fans. ** (ver 2) files -- added slots at the top of the box to route the LCD DATA CABLES, also added support /separation for each set of screw terminal sets - then on the cover, opened fan vent ribs for improved airflow and rounded inner mounting corners.
