DIY Whiteboard Markers Holder

I recently bought a whiteboard and I have a few old markers to write on it. Being made of steel, magnets stick to the whiteboard. I also happen to have old magnets from Displate, which are unfortunately single use (for the function of holding a Displate poster to the wall).

So obviously I can design and 3D print something to hold the markers and glue the magnet to the back of it so it can stick to the whiteboard.

That was a quick and easy thing to design and use.
