so the glass Ikea whiteboard doesn't come with a shelf for your pens and a scrub, so I came up with my own. The initial project had some flaws (like a little hole between the our wall and the triangle stress support and I have measured the height of the holding arm to the middle of the whiteboards screws so when the metal rod went through the hole it bend a bit), but the current design got fixed before upload :)

I was also thinking about changing the mount hole to instead being a pull-through hole more like hanger, but I didn't got much time yet to redesign it.
