This is for my Oral-B electric toothbrush there are two models so be careful. One will have a stabiliser that goes into the charging hole and the other will not have this so if you do not have an Oral-B electric toothbrush I would advise you go for the one without unless you are certain that it will also fit your toothbrush. 

This model is free standing and does not need supports unless your printer cant do a 6mm bridge which if you have an old school bed slinger I would recommend adding supports to it but the clip for the toothbrush head will not need supports.

It also has a head holder so that excess water after brushing can drip off into the funnel and be directed into a sink rather than getting over your toothbrush. It might be a small thing but it bothered me. It could also double as an extra toothbrush head holder so a spare is kept next to it for when it need replacing. 

Happy brushing :)

EDIT: The old file after 4 months built up gunk in where the toothbrush is held so the updated model has drainage there as well to prevent this problem which I overlooked. If you have the old file printed i would recommend reprinting but with this new model.

WARNING: I have not been able to test it but due to layer lines I believe it is susceptible to building mould. For safety I would say use PETG and a food safe coating on top if you want to use it for a long time as PETG is generally more food safe to other materials that most people who print will have but that alone will not make it safe. I will try update to see if it builds mould.

Please leave feedback and how your toothbrush handles so I can make the changes required to better this model.
