This is a minimalist toothbrush holder that can fit the majority of toothbrush models, requires really no time to print and prevents any contact between the bristles and the wall or the holder itself and is easy to clean, thus being more hygienic.
In the pictures you can see the V1 model at the left and the V3 at the right.
The V3 model has a slight snap-on feature, to better hold the toothbrush in place, but I still use the version 1 and it works perfectly fine for me. I made different tests for this snap hook interference with versions V2, 2.1, 2.2 and 2.3, which were either too tight or too loose, and that's why I did not include those files.
These were printed in SUNLU's PLA+ filament.
Fixed them to the wall using 3M high resistance adhesive which I got from here: Update 16/07/2019: still working after almost 3 months installed.
