My brshes were just lying arond everywhere, so I made this holder. I don't know if it is the best solution but it works for me. Designed to be made from 4mm material, I used plywood but I'm sure acrylic would also look pretty good.
Just in case my CAD program messed everything up, here are the dimensions for the files: top_bottom.dxf: 140x70mm; sides.dxf: 268x70mm; dividers.dxf: 248x140mm
Cut everything out. You need to cut every file only once.
Glue it together as shown in the picture.
- Use it! ;)
