I made my version of the great toothbrush holder.
This is a very good organizer for toothbrushes. Water flows directly under the object. Works great. The first version is a stand for 4 toothbrushes and a paste. The other is a brush stand only. Brush diameter hole is about 17mm.
Print time: 3 ~ 4 hours
It looks best in white.
The most practical material is PETG.
