This is an adapted version of budthedog's CR-10 Modified Filament Spool Holder to work with jantzenday's CR-10 Spool Adapter, and GRNTNKRL's CR-10 x-stepper spool holder design.

All three of the above mentioned designs are outstanding, but I wanted something specific for filament handling. I wanted my spool to remain parallel to the X gantry at any height and I wanted a universal hub design that could be used with this setup, as well as with my Anycubic stand-alone spool holder. GRNTNKRL's holder is intended to work with the Creality spool bar, which I don't have since my CR-10 clone is an ultra-cheap knock-off, and it needed to be a bit longer to accommodate the depth of the spool holder and width of jantzenday's spool adapter.

Budthedog's modified spool holder was the perfect length for my needs, but needed to be reduced to a 30mm diameter to fit jantzenday's adapter.

Having a nice round 30mm diameter to work with for the adapter made for a super quick and easy build for the insert which allows me to use jantzenday's design with my Anycubic spool holder. I'll try to get that part posted shortly in case anybody is interested.

UPDATE 02142022: I added an extra long tube for anybody who needs a 30mm spool tube that's 24mm longer than the original model. I was going to use the extra long tube with a modified version of jantzenday's adapter for Amazon Basics spools, but realized the long tube was going to break compatibility with the spool holders I have on my two acrylic printers, so I further modified jantzenday's design to fit the Basics spools on the original sized tube.
