Printrbot Simple Spool Holder

Printrbot Simple Filament Spool Holder/Coaster.

I couldn't find a Filament Holder I liked for my Printrbot Simple Metal, I designed one over a year ago, but it was too complicated, it used screws and bearings and still had issues. This one is simple, print in one run and your done! Plus it works great, you can leave your printer unattended and not worry about the spool jamming or falling off. Here are some of the highlights:

-Sits on top of printer saving desk space.
-All Spools sizes: Supports spools up to 95 mm wide and around 200 mm in diameter, I haven't seen any bigger spools, but if you need wider let me know, I can make an extension.
-Can leave printer unattended, I've tested with cardboard and plastic spools, they rotate easy (make sure you make your filament feed from the bottom like my pictures, it puts less stress on motor).
-Allow printer full Z access motion (up to 150mm) on all the spools I've tried.

**If your interested in mounting it on a table, let me know
