Big Thick Gyro Cube v2

thingiverse

Original Multiple Extruder Update: The "odd" and "even" sphere files were uploaded for easy color printing with dual extrusion printers. The supports object was also separated, allowing users to include or exclude it as desired or assign it to a support-material extruder. V2 Update: A second version including supports was created to address common printing issues at overhangs. This version can be found in the "with supports" file. Sphere #2 (second smallest) was cracked and fitted into sphere #1's (smallest) nib holders, with notches added on one side of the female nibs for easier assembly. The version with supports was printed at 70% scale, slightly larger than thing 40760. Design Details: The spheres in this version are 5mm thick, making them less fragile during printing. The "holes" have been cut with a flat inner edge, ensuring better closure and cleaner edges for vertically printed holes. The object is larger overall to accommodate the thicker spheres, requiring at least a 150x150x150mm print volume for full-size printing. It features large nibs with shallow departure angles to avoid overhang issues. Printing Instructions: The model can be printed without support material. Recommended settings include PLA, extruder temperature at 180°C, and a blue painter's tape bed at 50°C. Infill was set to typical 40% honeycomb with a 90-degree angle for better fill pattern alignment. A 0.75mm Z-lift on retract was used to avoid hitting any parts during large fast movements. Printing Experiments: Initial attempts were made with PLA, followed by ABS with a 0.5mm Z-lift on retract. PLA printing provided better results, but the vertical circles' closure still required careful monitoring.
