This whiteboard marker holder is inserted in the rail of a cheap whiteboard. Helps to store markers below the whiteboard so that they don't cover the useful space of the whiteboard.

Markers count can be adjusted via Autodesk Fusion by editing rectangular pattern (see the screenshot). Note that it depends on total width of one marker section, so make sure to update it if you adjust the holder. Remember to add fillets between sections for a smoother look!

Blueprint of the hook is included for ease of creating other hangable things for similar whiteboards.

NOTE: Requires supports, preferrably tree ones.
