self back trigger point massage

a self back trigger point massage tool . you can print it in a single print if bed is at least 255x255mm.. i ended in this design after a lot of trial and errors. I put it up of my shoulder and find the spot of pain. then i gently push it . make some up and downs in the spot. the relief is what you guide through the process! very robust design with one joint. no other materials needed to assembly. the final assembly is completely balanced and beautiful! you can use it as physics decoration when you aren't using it. maybe i will include a futuristic base for this in the future. all the parts are designed to fit exactly the bed of the x1c. (255x255mm). it works superb! i manage to relief my back pain at last! it only costs 245 grams and 6 and a half hours. i included all 3 stls too. i preferred 2 colors for this beauty! this is printed with petg. this is printed with ams but you can print the dual color if you pause print at 5mm.One more pause at 15mm. Assembly instructions: clean carefu
