Brush/pen holder for mugs
thingiverse
I got a broken Star Wars mug I didn't want to throw away so I repurposed it as brush holder. I designed this to separate brush, pens and small tools like qtips or tweezers. It also protects the mug in case you want to use it again in the future. And it have a secret compartment to storage microSD cards or something like that. It would fit any standard mug, but you can scale it to your convenience. Let me know in the comments if you want a a version to print each compartment separately.
