This electric toothbrush stand has a design that's partially inspired by the Daleks of Doctor Who and partially by the Viking Mars Lander. The specific toothbrush I designed it around has a diameter of 27mm, but the stand should accommodate anything from about 25 – 30mm. [And if you happen to know OpenSCAD, you can adjust
cutout_diameter for your specific needs.] The stand itself does not have a charging pass-through since this particular toothbrush takes a AA battery.
This absolutely requires supports to print correctly.
