Pressure Point Massager using recycled toothbrush vibrator

thingiverse

If you're a connoisseur of quality, you've probably invested heavily in top-notch toothbrushes - Oral-B's Pulsar toothbrushes are the crème de la crème. The bristles vibrate and thoroughly clean your teeth - but when they start to fray, it's a waste to discard the entire thing. Fortunately, the vibrating mechanism can be easily disassembled and repurposed into this clever item. Create as many as you need! To extract the core from the toothbrush, simply unscrew the handle and use a pair of pliers to carefully squeeze the battery and metal contact (without damaging the battery) and pull it straight out. Insert it directly into the button shaft. Alternatively, if you prefer the twist-on option, print out those two parts - twistbase.stl and twistshaft.stl - extract the core from the toothbrush using the previous method. This time, however, bend out the outer contact a little so that the battery can't touch both ends simultaneously (just a millimeter gap will do). Insert it with the button in the 'on' position and screw on the cap. Note: The twistbase is specifically designed to work with the twistshaft - they're not compatible with any of the other three parts! If you found this useful, be sure to share a picture (it makes my day every time someone prints something I designed) and check out my other submissions, which are almost as diverse as they are practical and numerous: http://www.thingiverse.com/3E8/designs Enjoy! March 30th, 2017 update: Skirted versions have been added, which print more easily on average entry-level build environments (like mine).
