thingiverse

Here is a way to re-use old Oral B electric toothbrush: 1/ Print the adapter 2/ Insert an M10 nut into a plastic tube (0.63 inch OD in the photo, 0.51 inch ID on the photo, electric housing tube 16/13 mm) using a heat gun. Make sure the nut is inserted far enough that the plastic retracts behind it and it does not come apart. 3/ Insert the threaded part of the adapter into the nut (it may be challenging at first, but you can use a tool to help). 4/ Insert the toothbrush (it will fit tightly) 5/ Brush your teeth This adaptation is especially handy in case of an electricity failure. Printed with 0.2 layer height, 100% infill, starting from the thread, without support. All files are provided for you to improve and customize as needed.
