I designed this unit to hold art supplies like pens, drawing pencils, markers, and brushes while i worked on my pieces, my windsor newtons recommend tip up to allow the air to wick up the remaining moisture so it made since to have something. I liked the 45 hole design but I also wanted to add room for larger brushes so I also created a second top option with 29 small holes and 4 large holes. I also had a friend friend request an angle based option. In order to assemble this you will need to print the top file and the base file of your choice this will print all 4 of necessary posts to make a solid unit. This was designed as a friction locked concept and should require no glue. I printed this at 220c nozzle, 60c bed with Inland Black PLA Pro at .2mm layer height, 2 shell walls, and 15% infill gyroid, but your can choose whichever infill you'd like.
