Prusa i3 Spool Holder

I've seen a few spool holders on here, but most designs require some form of bolt / axle to join everything together. Since I had a few bearings around from a previous design I thought I'd try to build something which only needed those.

It's something of a work in progress, but seems to be stable enough now to be worth sharing. If you're interested in printing this, I'd advise taking a look at the CAD files on [OnShape](https://bit.ly/3a429Tl) to check that the design works for your printer. I have a Geeetech version of a Prusa i3, and it seems to work well here, but your experience may vary.
