Yet another whiteboard marker holder. Holds 5 markers and sticks to the board with four 10mm x 10mm magnets, no clue required.
I was not quite happy with the other marker holders I found, so I made my own design. Sparsely commented OpenSCAD file included for anyone who wants to edit the design.
Should print fine without supports. You probably want at least 30% infill to make the narrow bits sturdy enough.
