Closed spool roller
thingiverse
I'm designing a closed 2-spool roller system. The design requires two exits for the filament, which will be added to meet the project's specifications. The standard box design features Ø15mm holes that maintain both the axes and the filament exits, ensuring stability and functionality. All red components are printed using TPU material, while other parts can be printed with either PETG or PLA. To complete the system, four 8mm rods will be needed, along with eight 6001 ball bearings (12x28x8mm) for smooth operation.
