Rainbow Storage Box (9-Tier)

Have leftover filament in many colors that you can’t seem to use up? Why not print a simple storage box? If you still have more material afterward, just print another one with a sequential number. These boxes can nest inside one another. Nine make a complete set. ‌Progressive sizing design‌: The outer diameter of each tier decreases by approximately 3 mm from the bottom to the top, enabling natural nesting. 1.After storage, the overall height remains uniform. Currently configured for 9 tiers, each layer is printed separately, allowing for flexible combination and disassembly. 2‌.Print parameter optimization (based on 0.4 mm nozzle + PETG)‌ Layer height: 0.2 mm (within the optimal range of 0.08–0.28 mm, balancing speed and precision) Nozzle temperature: 240–245 °C (ensures good flow of PETG) Bed temperature: 75–80 °C 3.Based on personal testing, perfect prints can be achieved without enabling the wipe tower. When printing sequentially one by one, up to two boxes can be successfully printed per spool.
