Small enchancement made 150607: Simple toothbrush holder for braun/oral-b type machine-toothbrush shafts, to share and modify. I made it just for fun. Enjoy! You can choose the number of toothbrushes it should hold when tou compile the openscad code. Or just choose 2,3 or 4 from the included stls. Can be printed without supports. Openscad source included. Please play around and improve. please give feedback and share :-) To use sunction cups, you may need to change the default diameter of the knob. see source file. Default is 10.5 mm, 3mm thick. Difficult to explain this in words.
