Filament Spool Hub

thingiverse

The design revolves around using standard 8x22x7mm skate bearings and an 8mm rod/axle. This hub makes it easy to print and assemble. A challenge arises when trying to secure the brace locking ring without having three hands. Most people face this problem, including myself. To overcome this obstacle, I use a simple fix by placing a small rubber band around the end until the ring clicks into place.
