chalk and eraser holder

thingiverse

I created this at my workplace because we required something like it. It was developed quickly so it doesn't have a lot of refinement to it. I'm pleased with how it turned out; I didn't take any measurements but it functions perfectly well. Some minor adjustments could be made, but I don't think they're necessary. As you can see from the pictures, it's designed to be pinned onto a bulletin board, though nails would also work if needed. Feel free to experiment with the design. If you do, I just want to see what changes you make to it.
