ToothbrushHolder.foocad

A wall-mounted toothbrush holder for 4 toothbrushes and toothpaste. Each of the 5 holders are detachable for easy cleaning.

Similar shop-bought items do not have the long tubes, which is a problem. Either the holes are too small for the brush handle, or the toobrush head touches the holder (yuk!).

Each tube has a small hole at the bottom for drainage.

Print Notes

Due to the height of the tubes, a large brim is recommended.

Use the customiser to print shorter tubes for child toothbrushes.

Improvements

Make the toothpaste insert slightly wider.
