This is an electric toothbrush inverted stand. Having the brush head pointed down prevents the wet brush from dripping all over the handle. Print on its back. No supports needed.
Update 7/11/25 - My kids wanted a “cooler” looking one, so I think I made it pretty cool with speed holes for faster drying?
The author remixed this model.
This is a taller version of @ShaneTory_379494 's “Electric Toothbrush Stand Upside Down.”
The original version I printed was too short for my Oral-B electric toothbrush, causing the brush head to come into contact with the waste liquid reservoir. I increased the depth of the resting cup slightly to add a bit more balance, enlarged the waste liquid reservoir, and also removed the -z lean from the internals, as I did not see a solid reason for it.
This is drawn from scratch by me, but I heavily worked off ShaneTory's model, bc I like the form.
