I confidently told my mother that I could print a holder for her Wisp toothbrushes, but imagine my surprise when I struggled to find one. One quick remix later, and she has a nice little holder that she can throw into her purse.
I had to use a brim on the cover part, but no supports needed for either. Depending on your printer, you may need to adjust the sizing on the cover a little bit to get the desired slip/grip ratio.
The author remixed this model.
