Toothbrush

Based on the idea of my previous model of a TOOTHBRUSH with changeable TOOTHBRUSH HEADS, I present a new design proposal for more sustainability and saving for resources.The TOOTHBRUSH HANDLE could be made of bamboo (New Trend).The method of screwing the TOOTHBRUSH HEAD directly into the TOOTHBRUSH HANDLE'S HEAD is surely more safety in comparision with a fastening by a detachable clip connection, but more complicated by using an additional tool like - for example - a screwdriver.If you have a "Euro 2 Cent" coin, you can use this coin for closing and opening.The coin has an outer diameter of approx. 18.8 mm and a thickness of approx. 1.7 mm.The used thread is M3 x (0.5) and modeled with theoretical values.The complete assembly is available as a STEP file (.stp) only.Most of the components are available as STL files (.stl) additional.
