This is a awesome fidget spinner, and you don't make it. You print it! It's all in the file. There's only one step. Good Luck!
Step 1: Ready, Set, Finish!!!
One step only!!! 3D print the file I put in the intro(that's the super spinner). then use a glue-gun or super glue to glue the 2 sides of the spinner together. Then put an axletree on the spinner(I know it won't fit). Then hammer the axletree in. Also the file you printed will also have the spinner's cap. Put one on each side. TA DA!!! FINISHED!!!
