Filament spool

thingiverse

Yes, another filament spool designed with precision! Advantages abound: It features a large, 100mm center that prevents filament cracking and deformation, while its 195mm diameter makes it easy to hold 1 kg of filament. Plus, it fits neatly onto most 3D printer beds. The design boasts lock holes for both the start and end of the filament, ensuring a secure grip. A substantial shaft measures 32mm in size, fitting snugly into most 3D printer spool holders. Construction requires only two M4 screws - no other parts are needed. To minimize material usage and reduce printing time, I optimized this design to include minimal extrusions. Most filaments rely on a center tube; not this one! Instead, it utilizes only the required 2x M4 screws to assemble both parts of the spool together. Its robust construction is complemented by a generous 100mm center that maintains 3 mm filament straightness during winding. When unwinding or reeling in new filament, the holes serve as steady supports for your precious roll. The Lyman-type winder design incorporates support for where the winder motor rests on the edge of the spool - perfect harmony between machine and printer! For convenience's sake (or curiosity?), see the related winder at http://www.thingiverse.com/thing:380987 Additionally, it pairs perfectly with the filament maker, an impressive print featuring a clever filament puller that's also accessible here: http://www.thingiverse.com/thing:677144 Follow these simple instructions: 1. Print the design using your favorite material - ABS works well at 0.3mm layers and 25% fill. 2. Don't worry about supports, as the holes have tiny plastic guides for secure printing. 3. Mount both spool parts with precision; only two M4 screws needed, utilizing opposite screw holes will do. 4. Install one M4 nut into each nut trap - simply heat the nut with a lighter or soldering iron to firmly secure it. 5. Success at last!
