54mm Bore Spool Mount

thingiverse

I designed a spool holder for my A8 printer because the existing one was lacking. The filament would often snap as it pulled on it, and I wanted to ensure consistent results from my reliable supplier. Since all my spools have the same bore diameter, I created a part that locks in place due to its fixed diameter. With some 688ZZ bearings on hand, I decided to finally make this design. While it may not be the most cost-effective solution, any suggestions for improvement would be welcome. I'm using it in conjunction with another thing from Thingiverse: http://www.thingiverse.com/thing:1743397. Print Settings: Printer: Anet A8 Rafts: Doesn't Matter Resolution: 0.2 Infill: 35% Notes: I printed with a 0.2mm shell thickness, or the screw part would tear itself off. This design is made for the threaded rod that comes with the Anet A8 printer and two 688ZZ bearings. Any bearing 16mm in diameter should fit in theory. Post-Printing: Bearings: I simply put some hot glue along the edges of the bearings, which holds them in place just fine for my purposes.
