This is a toothbrush holder suitable for both regular toothbrushes and interdental ones. In its current form, it can hold 5 regular and 10 interdental toothbrushes. The holding system for regular toothbrushes is inspired by http://www.thingiverse.com/thing:9056. However, my holder has clips printed horizontally, so they should be more elastic. It is wall-mounted using a single 3mm woodscrew. It has 8mm holes for interdental toothbrushes (which usually have 7 to 7.5mm stems). Each regular toothbrush I have tried fits, some of them are a bit loose, but still they are safely held. A possible improvement would be to have two mounting holes instead of one. Also, it looks tiny enough, so the next version will probably have 15 or 20 slots for interdental toothbrushes (three or four rows instead of two). The photos are from the previous version, where the slots for the interdental toothbrushes were shorter, and the screwdriver hole created a gap between the two slots in the middle. The current files have 2mm higher cylinders for the interdental toothbrushes, so this problem should be gone. UPDATE 2013-11-19: Apparently my family has decided that five toothbrushes is too small number :-), so I had to create a larger version of this holder. Now it has three rows of interdental toothbrush holders and 9 places for regular toothbrushes. I have also added a horizontal protrusion to the back in order to fit into the space between the tiles and to avoid rotation around a single screw. Comment it out in the OpenSCAD source if you plan to mount it to the flat surface. UPDATE 2014-05-05: modified the clips' connection to the holder body - made the connection round in order to avoid a weak point in the inside of sharp corner. Also modified the rear protrusion slightly. I have printed it on Prusa i3 using FormFutura white 3mm ABS. 2 perimeters, 2 top and bottom solid layers, 0.15 mm layers, 20 % infill. Next time I will probably use three top and bottom solid layers, because the top of the central part came out with space between the filaments. Make sure you have your heated bed well tuned: my first print did not hold some of the clips well, and they come out distorted (see the photos). There is no need for color printing here - the toothbrushes themselves provide colorful-enough look. UPDATE 2013-11-19: The 9x3 version has been printed with 0.25mm layers, 10% infill, two perimeters, three top layers and two bottom layers. Looks good. UPDATE 2014-05-05: I suggest to cure the printed thing in acetone vapours to connect the print layers better and to get a glossy finish.
