Electric toothbrush head cover
thingiverse
Since I couldn't find one like I needed, I submit my version of a case for electronic toothbrush head. PETG is safe for food contact, but keep in mind that it is hygroscopic (absorbs water) and bacteria can collect inside material's pores. For this reason, it's better to clean the cover often (search for the method that better suits your need). I designed it to be printed without support and encountered no problem printing (see pictures). Of course, brush is not included! ;-) It has a slot to insert the finger nail to simplify the opening. I suggest to keep the "male" (M) part on the bottom when opening (to decrease the chances of brush head to fall off) and the "female" (F) part when closing (to facilitate the interlock). To close it, lock the "head" before the "tail".
