Brush Holder( with locking mechanism)

Started my new hobby which is model/miniature painting. I recently learned that brushes are meant to be stored horizontally, not vertically so I decided to make one. The box is round in the center, but hexagonal outside, so it can lay flat on the table without any problem. The two extra holes on the box body are for holding the brushes in place( with Zip ties) if you ever need to transport them but dont want to ruin the brush-head Box height is 230cm (usable height is 220cm), inner diameter is 6cm. If you need a different size, feel free to scale them as needed.
