4L米桶干燥箱终极支架(4L dry box ultimate bracket)

This integrated 4L rice bucket stand may represent the optimal design for a 4L rice bucket stand(Numerous 4L rice buckets exist on the market, visually similar yet varying in base dimensions. Prior to printing, meticulously compare measurements to prevent material waste. Utilize your slicer’s measuring tools or grid counting for precise assessment. Printer tolerances differ; should the axle fit loosely or insecurely, fine-tune scaling as needed. Some smaller bucket bases are exceptionally narrow, requiring central axis extension for adequate support)

Advantages: Central axle-free, preventing filament entanglement. Hygrometer accommodation. Capacity for at least 250g of desiccant.

Due to the rice bucket’s confined space and dimensional constraints, initial attempts at a bearingless design proved problematic, yielding inconsistent positioning and potential filament tray jams (printer tolerances vary). The bearingless approach was therefore abandoned.

Separate purchase of bearings is required, specifications: 608ZZ-8*22*7

Support material is necessary when printing the lid. Utilizing a support interceptor to obstruct ventilation holes is recommended for expedited printing.

July 17, 2024 Update:

All component dimensions have been refined, ensuring compatibility with both Tianrui’s narrower trays and Bing’s extra-wide trays. Roller bearing installation orientation has been modified. The Mi thermometer clasp has been repositioned outwardly.

Precise alignment of roller bearings and axles is critical; misalignment will result in filament tray jams.

Deviation from these installation guidelines will invariably lead to filament tray jams.
