I didn't like any of the existing whiteboard marker holder designs, so I made my own. Specifically, this was designed to hold many markers with minimal space, as this whiteboard lives in a high-traffic area in the kitchen.
Print in 3 parts, Top, Bottom and Middle. I printed it with zero tolerance in the connection between different parts, so it took a lot of xacto knifery to get it to fit, and once it fit, it was impossible to take apart, so I haven't tested it with the other tolerances - 0.10 mm, 0.15mm and 0.20mm. Use your own judgement there.
Holds 7 markers and an eraser.
I used 4 vertical lines of a roll of a sticky magnet, but the adhesive failed, so I used super glue to improve the adhesion, and it's been holding up now for a few days.
