Some brush caps for protecting the hairs of model paintbrushes.

I got sick and tired of those little transparent pieces of tubing that kept falling off and being a pain putting them on without touching the delicate hairs of the brush.

So I made these. They're designed to fit some generic brushes i got from Aliexpress. They are simple, print relatively quick and snap right on, so no need to fiddle with them.
I also made them partially open to see the brush size directly instead of relying on the numbers.
Two versions: one that snaps on and one with an extra ring in the middle for more security, although IMO the vanilla ones work perfectly as they are.

Print them upright, with a brim, no supports needed.

Feel free to modify them as you see fit for your own use case.
