This Thing is a spool holder for 3D printers which mounts to a rotating lazy susan, allowing for less binding than traditional and older spool holding systems where the spool simply rests on a fixed rod or tube. This holder also allows for varying thickness and diameter spools to be utilized and securely mounted in one place unlike others where they hang off or are very loose.
This holder supports spools from 1.9" in center diameter through over 3" and as wide as 4.75".
For the mounting of this Thing, a 4" lazy susan must be used in conjunction with a minimum of four bolts and nuts.
This is the lazy susan I used, personally.
When done, simply assemble and mount anywhere on your printer, wall, stand, etc.
I apologize for the low print quality seen in the photos, as the part was printed on an old Solidoodle with sloppy belts, worn bushings, and no part cooling whatsoever. That said, this part is easily printed on just about any other printer out there, so long as it fits the physical constraints of the build volume.
