Anycubic Spool Caps

thingiverse

The original spool holder of my Anycubic i3 Mega was subpar, as the filament movement was decidedly uneven. To rectify this issue, I designed and printed several caps that would ensure the spool is perfectly centered. The existing caps available on Thingiverse failed to match the filaments I later purchased, and their thickness made them cumbersome to use. My goal was to minimize material usage for this project, as I am confident you can further optimize these designs if needed. To secure the spool, I used small rings that snap onto the caps. To assemble the filament holder on my Anycubic, I first attach a ring, then a cap, followed by the spool, another cap, and finally another ring to the pole of the filament holder. This process requires printing two of each component. With these custom-designed parts, changing filaments has become significantly easier, eliminating the need to print separate caps for each spool. I have uploaded designs for various filament spools to accommodate different sizes. For my prints, I used PLA with a 0.2mm layer thickness and no support material. Edit 2018/12/12: To enhance stability, I added a bar and a barcap that fit snugly onto the spool caps. For optimal results, print the bar lying flat on its side with a raft. This approach worked successfully for me.
