Whiteboard marker storage salvador-richter

I recently bought a whiteboard for my daughter.
Now it appeared the given holder for the whiteboard pens did not fit for the pens I got.
So I created a holder by myself and printed it. I have created a a set for a variing number of pens.
If you need another number of pens, another diameter for the pens or some other modification just drop a note and I will provide.
