It's a holder for a pair of toothbrushes. I wanted to use existing holes under bathroom shelf, that's why the backplate is so tall. I also added shorter version if that suits you better.
Pegs for handles and heads are printed separately to allow for easier printing without supports. The ones for handles can be screwed in place with single M3 bolt, the ones for heads are press fitted or glued in place. (You can just glue in place both and it will work just fine)
The author marked this model as their own original creation.
