These spinners are great fun on your desktop, letting them whack into things or each other, just don't use near your drink cups! You'll need a 1-inch ball bearing for the center and 5/8 bearings for the arms. They won't spin as easily in your hand like a normal 608 bearing spinner, but on a flat surface they spin a long time on the 1-inch ball. You can find 5/8 bearings at https://www.amazon.com/gp/product/B007B2AD70/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and 1-inch bearings at https://www.amazon.com/gp/product/B00S1N4B9E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1. Check out videos of them in action on YouTube at https://youtu.be/BD5cj8IXTeE and https://youtu.be/qkYoRb3bI3o. Print Settings: Printer Brand: SeeMeCNC Printer: Rostock MAX v2 Rafts: No Supports: No Resolution: .3 Notes: I printed at .3 layer height, 5 perimeters, 0 top and bottom layers, and no infill. Printing with 0 top and bottom layers gives you the groove in the arms, but you can cap them if you prefer. Five perimeters will make it a solid object so no infill is needed. The center bearing should press in easily, but is tight to pop in; the outer bearings may need scraping. I use a pocket knife to scrape around a little bit and knock down the ridge; then I try to push them in. The rings they fit into are cut out with a sphere, so they're wider in the middle. Just scrape enough so that you can pop them in with some force and they'll stay in fine.
