Small spool adaptor for Kossel Spool Holder

I made Chris Parishs' Kossel spool holder which works great for full size spools, but not so well for the mini-spools with 32mm spindle holes. This is a simple adaptor that fits over the bearing of Chris' design to allow these smaller spools to fit securely.

Prints OK without inner support but might look a bit untidy inside....add support if that kind of thing bothers you.
