My wife asked for a toothbrush caddy. She wanted something that was a two-tiered open air design that would accommodate multiple brushes and a tube of toothpaste. She wanted it to be multiple colors too (black and white).
The tabs on the two side walls can be very tight, it took me sanding them a little to get them seated fully. The feet are meant to be glued in place.
If you end up printing one, I hope it provides you many years of toothbrush storage happiness!
