Big Ol' Rudimentary Spool Holder

NOTE: Scale to 1000% in slicer. Autodesk Inventor decided to scale the whole thing down when I exported it.

Want a super basic, robust, 3D printer filament spool holder (or, any spool shaped object for that matter) that doesn't require any assembly, complex instruction, extraneous hardware, or intelligent thought whatsoever? Then this is the spool holder for you! Introducing the Big Ol' Rudimentary Spool Holder by yours truly. This spool holder is 200mm x 200mm to should fit on almost every entry grade 3D printer. The shaft is 1.75 in in diameter and 5 in tall, so it will fit almost any spool and will allow for the stacking of 2 spools. Spools are mounted horizontally, and I recommend placing some duct tape, electrical tape, hot glue, or any other high-friction material to the underside to keep it in place.
