A very simple holder for two Oral-B toothbrush heads.
Uses wire instead of printed studs because it's stronger, and less susceptible to water damage. Heads are stored at 45 degrees so any water drips off away from the holder.
You will need two pieces of 2mm wire bent into hairpins about 300mm long and 8mm wide.
I've included the OpenSCAD file so you can add more toothbrushes, change the distance between heads, use different wire, add screw holes, or whatever else you want.
