3380 Dry Box - AMS Spool Drying Case Spool Holder

Utilizing inexpensive 3380 storage containers(￥15) and AMS-Lite spools, this provides a sealed, dry environment for filaments;

3380 storage containers can be vertically stacked, saving space compared to rice-bucket methods;

Precise measurements ensure a perfect fit, eliminating unnecessary frame sizing;

Each holder uses less than 100g of filament and takes approximately 3 hours to print, saving both time and materials.

Can hold approximately 250g of desiccant, reducing internal relative humidity to 4% within 3 days;

No hygrometer slot included, as the desiccant in my rice-bucket drying box maintained relative humidity at 10% for 6 months, requiring only a periodic hygrometer check after six months to assess desiccant activity.

Spool Compatibility Testing:

Compatible: R3D, Tianrui, Tu Zhu, Aliz, Sanlv, etc. Spools with diameters less than or equal to 20cm;

Incompatible: Bing separable white plastic spools (due to friction with the outer walls)
