Monoprice Maker Ultimate Extended Filament Spool Holder

This is a simple extended spool holder that will allow a Monoprice Ultimate 3d printer to hold larger filament spools such as Monoprice's own branded 1 kg filaments. The outer diameter is sized small enough to also allow using smaller spool diameters. This should work just fine on a Wanhao Duplicator 6 as well.

I printed it in Cura using a shell thickness of 1.6 and %50 fill density with common PLA filament and it feels secure.
