For the discerning hobbyist with a need for an overbuilt spool holder that fits double height (as opposed to double wide) two kilogram spools.
This model has everything! The shaft is reinforced by a long bolt to make it really, really hard to snap despite the suboptimal print orientation. The sleeve rides on two ball bearings that are held in place with printed C-clips. And the whole thing can be printed on a Mk3/Mk4.
In terms of material choice, I think the model is burly enough that probably anything would work, but the retaining clips need some flex. Do not print the retaining clips out of PLA or any fiber-reinforced filament or they will snap. Trust me, I tried. I personally used Polymaker PA-6 GF for the base and Polymaker PolyLite ASA for the sleeve. The model is designed to be assembled with a light interference fit. I have included two test models to make sure the bearings and bolt will fit correctly before committing to the large amount of time and filament it requires to print the whole thing.
You will need:
A 3D printer
Filament
One XL Spool Holder Base
One XL Spool Holder Sleeve
Three XL Spool Holder Retaining Clips
Two 6804-2RS (20x32x7 mm) ball bearings
One 200 mm M6 hex bolt
One M6 hex nut
Slicing:
Base: 0.3 mm layer height, 3 perimeters, 30% support cubic infill
Sleeve: 0.15 mm layer height, 3 perimeters, 30% cubic infill
Retaining clips: 0.3 mm layer height, 3 perimeters, 100% infill
I recommend using a 0.6 mm nozzle to save time and increase the strength of the part.
Assembly:
- Slide the bearings onto the shaft.
- Snap the three retaining clips into their grooves.
- Insert the M6 hex nut into the hexagonal recess on the base.
- Insert the M6 x 200 mm bolt into the shaft and tighten. It doesn't have to be terribly tight.
- Slide the sleeve over the bearings. There is a small indent on the base that matches up with a protrusion on the inside of the sleeve to prevent it from sliding off in operation. It may require some pressure to seat the sleeve.
- Profit!
