Another Universal Spool Roller

thingiverse

This is a versatile spool roller designed to fit various size spools without disassembling the entire assembly, allowing for effortless filament changes. To assemble this component, you will need to print two identical parts. Four bearings are required, specifically the 608ZZ type with dimensions of 8mm inner diameter, 22mm outer diameter, and 7mm width. To install the bearings, attach two to each female part, pressing them into place until they snap securely. Once the bearings are seated, carefully press the male part onto the female part, ensuring a snug fit. If necessary, use a vise to apply pressure during assembly. The assembled roller can be secured in place using 1/8" screws, which attach to recessed squares on one side of the component. Alternatively, mounts can be attached in a fixed location using the same type of screws. A secondary roller set is designed to slide into a channel, accommodating different spool sizes and facilitating easy filament changes. **Print Settings:** * **Rafts:** No rafts are required. * **Supports:** Supports are not necessary for this design. * **Resolution:** The recommended print resolution is 0.2mm for optimal results. * **Infill:** A 20% infill density is suggested to achieve the best balance between weight and structural integrity. **Assembly Notes:** * Walls should be printed with a thickness of 1.2 mm to ensure stability and durability.
