This precisely shaped part is indented to hold a toothbrush of the brand “Dr. BEST” on your bathroom mirror or wall tile. The fit to the widely sold generic suction cups that come with a 16mm thumb screw.
Printing is totally uncritical. No supports are needed. Basically any material should do (tested with PLA and PETG). The default values of 2 perimeters and 15% infill are fine, although I have used 3 perimeters and 25% gyroid infill.
Your satisfaction is my reward. Please leave a like, or even better post a make, if you like this design. That really makes my day.
Happy printing
