Kudos to Yagokun for his original "Baby Tooth Smile"
(http://www.thingiverse.com/thing:2058973) and the remix by Cyborgdaron.
For this remix, I've added 4 angled holes large enough to fit good sized brushes and a drain system.
Model size is about 5" tall and 3.25" wide. Takes about 11 hours to print on my CR-10.
Forgive the pimples on my first print, was having some issues with Simplyfy3D... actual model is very smooth.
Added another version that has a simple curved partition to allow both brushes and a toothpaste tube. Thanks to TheTWIGS for printing that version to test. See his make for a photo: https://www.thingiverse.com/make:494830
Print it smaller and you have a nice pen/pencil holder. :)
This might actually print without supports but I turned on bed supports only and it didn't add much time to the print and produced a nice undercarriage.
If you sometimes have problems getting things to stick to your bed surface, I would enable a brim for this print. Some users have experienced the feet falling over before they're joined together. You could also try moving the print down 4mm or so which would give the feet a larger surface to start with.
