Back Massage Roller for Spherical Crystals

thingiverse

This was born out of frustration. I bought this roller thingy from Sephora: https://www.sephora.com/product/crystal-facial-roller-set-P444013 But I was sad that you could basically only use one of these at a time. I am extra AF and wanted to use all 3 balls at once. JUST BECAUSE. So this monstrosity was born. I think I printed this out of Taulman's Bridge Nylon. It's 100% infill because I like to use it to give my boyfriend a nice ROUGH back rub. And yeah, I apply a lot of force to the handle and it hasn't broken... yet! Ergo ish handle. I think this was remixed from one of the 'slingshot' files on Thingiverse but I honestly can't remember. Sorry! The three holes are 'self tapping' so just grip n' twist those bad boys in. You can add glue or Loctite or whatever if you are extra anal. I didn't bother tho. It has lasted many a back rub!!! :D If you refrigerate it, even better, especially after a workout or in the hot summer... Included the Fuson360 file incase you wanna modify it or whatever. A good program for modifying STL files is Materialise Magics but I realize not everyone has that...
