Toothbrush Organizer
Organizer for Oral-B toothbrush and head. It offers also a place for the toothpaste and interdental brushes.
This is my first customizable thing. (The number of each of the holders can be changed,. If you don't need a particular holder, just set the number of that holder to zero.)
The print in the picture was my first try. I made the toothpaste holder and the interdental brush holder smaller by 0.5 mm and arranged the holders somewhat more dense.
