Spool of Thrones Holder

Many school printers are designed for filament spools of one standard size. However, one way for schools to save money is to buy spools in large bulk sizes.

However, these large bulk spools will not fit in / on the factory spool holders.

You will also need a scrap section of 1/2 PVC pipe or dowel. I've used a broken broom handle as well.

I designed this to fit the large 2.2 kg (5 lb) spools from colorfabb. This is high enough to give you clearance for any commercially available spools.
