This is a tooth brush holder with your profile picture. It fits a standard 40x40mm (1,57in) "wallet-kind" photo, so you'll never take the wrong brush again! I glued mine to the wall with doble-sided-tape, also has a hole for a screw but with tape is more than enough. Each holder has a little hold at the sides so you can print a few and stick them together (see the pictures).
Print Settings: No Supports, Resolution: 0.25 Infill: 35%
Notes: Print it with supports if you are going to print at least two, and stick them together. If you're gonna use only one you can avoid supports.
