Back Massage Roller for Spherical Crystals

thingiverse

This was born out of pure frustration, so I bought this roller thingy from Sephora: https://www.sephora.com/product/crystal-facial-roller-set-P444013. However, I was sad to discover you could basically only use one of these at a time. As someone who's extra, I wanted to use all 3 balls simultaneously, simply because I can. So, this monstrosity came into existence. I printed it out of Taulman's Bridge Nylon, which is 100% infill because I like to give my boyfriend a nice rough back rub. And, yes, I apply a lot of force to the handle and it hasn't broken yet! The ergo-ized handle was remixed from one of the "slingshot" files on Thingiverse, but I'm not entirely sure which one. Sorry about that. The three holes are self-tapping, so just grip them tight and twist those bad boys in. You can add glue or Loctite if you're extra meticulous, but I didn't bother. This thing has withstood many a back rub! If you refrigerate it, even better – especially after a workout or during the hot summer months. The Fuson360 file is included in case you want to modify it or whatever. A good program for modifying STL files is Materialise Magics, but I know not everyone has access to that...
