Expanding Brush Case

This is a brush case that was requested by a friend. He wanted a case for his daughter that could hold a variety of brushes over the course of a school career. This case can be expanded from 20cm to nearly 30cm by twisting the inner cylinder and then latching it at one of the set heights. The cap is a simple ‘squeeze to release’ design so ease of use may depend on your chosen material. I printed this in translucent PETG (and cut in the daughters name) for an interesting effect and to be able to see the workings.
