UPDATE2: Use this Remix instead, works better: https://www.printables.com/model/1084799-hoto-vacumm-secure-brush-holder
When having the brush on, it is not fixed on the top, so it moves down and is very annoying. This solves that.
Print with Brim and Tree Support
UPDATE: I found this works, but doesnt hold super well over time, maybe the thing sticking out could be a bit bigger.
