Knitting or Crochet Spindle

My wife really likes this model a lot but I noticed that I couldn't find it or something similar here on Printables so I wanted to reupload it. It uses a standard skateboard bearing to spin.

From the original upload:

Print both parts, mount a skateboard bearing to the thin spike, and push the large spindle down until locked. Push wool onto spindle. Knit / Crochet in peace.
