Batman Spinner

I redesigned www.thingiverse.com/thing:1849269, which was off-balance and had undersized bearing holes, forcing me to recreate it with Solidworks and make necessary adjustments for perfect balance. I included a 17mm x 6mm x 6mm bearing adapter so users can take advantage of ceramic ball hybrid bearings that significantly extend the spinner's lifespan. A suitable option is available at https://www.amazon.com/gp/product/B06Y2HH6Z7/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1. Users have two bearing options: a 22mm x 8mm by 8mm 608 or the included 17mm in the center, with the outer bearings used for weight. Grip caps and flat caps are also included to fit each bearing size. Flat caps are designed for use on the outer bearings while grip caps are intended for the central bearing. To install the bearings, I recommend using a small Arbor Press or a vise. A socket matching the outer ring of the bearing is necessary; apply gentle pressure when pressing in the bearings and adapter to avoid cracking the plastic.
