Custom Modular Black Widow Spool Holder (8020 Extrusion)

thingiverse

This is my custom spool holder engineered for the TEVO Black Widow's 8020 extrusions. The spool holder was designed with versatility in mind, capable of accommodating any number of spools regardless of width. The height and diameter of this design guarantee compatibility with various common spools: - A 6.5" diameter, 3.75" wide spool with a .78" inner diameter for the spool holder - A 6.5" diameter, 3.375" wide spool with a 1.25" ID - An 8" diameter, 2.75" wide spool with a 2.05" ID - A spool measuring 9 cm in width (3.5 in), 20 cm in diameter (7.87 in) and featuring a 3.2 cm (1.25 in) hub hole - A spool measuring 18 cm in width (7 in), 20 cm in diameter (7.87 in) with a 3.2 cm (1.25 in) hub hole Simply print two rod retention parts, two end caps per spool, and the necessary number of end supports and middle supports. Eight M3 15mm screws and four M3 2020 T nuts will also be needed for each spool. The end caps are designed to fit snugly onto 1in schedule 40 PVC tubing. Two details I overlooked were the addition of filament clips and tapering the end caps to facilitate easier insertion, but perfection can be a curse!
