I've use the holders from Pedrofernadez design. Mesh them together with a platform and brush holder added. A friend asked me to design something similar to the item he saw on a Facebook group page but wanted a better lay out He wanted a more practical lay out and the brush holder positioned appropriately.

I've added another file which is the same but has the brush holder straight up. I have not printed this out yet. If you do, please post your builds

Update 10/04/23:Revised an old design and added another.

Update 4/22/19: Cleaned up the original file as it has some issues
