About this 3D model

Two versions of my Nickel spinners. Each one holds 9 nickels for the weights. One version uses a C size yoyo bearing and the other uses a 608 size skateboard bearing. I do 4 solid top and bottom layers with 30% infill for the spinner body and 50% infill for the buttons Spinners do not need supports, but the buttons do for the recessed thumb indent. I like to fill the indents with flowable silicon when they are finished for nice grips. All of the holes for the nickels and bearings are a VERY tight fit so you need to press them in with a press or hammer them in but they need to be tight like that to hold the bearings and nickels in without them falling out. Enjoy and happy spinning!!
