Filament Box, Upgraded Version (Multiple Spool Sizes, with Desiccant Box, Optional Heated Hygrometer)

Building upon my previously released filament container, I've implemented several enhancements

• Incorporated a desiccant compartment, concurrently serving as filament spool support
• Integrated label slots accommodating 30mm x 30mm cards under 0.75mm thickness

• Two label application methods are available: acrylic paint markers (approximately one dollar per marker) or MakerWorld's custom label creator

  Baseplate and thickness settings are illustrated below, modifications are indicated in red, border width is set to zero

  

• 

• The desiccant compartment readily accepts silica gel desiccant; other desiccants remain untested, aperture width is less than 1mm

Furthermore, the desiccant compartment is designed for hygrometer integration, although in-situ results are somewhat suboptimal

The hygrometer accommodates the dimensions of a circular Topjoy hygrometer, with a 45mm diameter; commercially available embedded circular hygrometers are compatible provided dimensional congruity

Assembly Instructions:

• During closure, maintain a horizontal orientation, align with one latch, and gently slide it along the edge until fully secured. Press firmly around the perimeter after initial latch engagement

2024-11-10 Update:

Employing transparent material and a polished finish for the lid enhances hygrometer visibility

Functionality remains largely satisfactory

Simultaneously, I experimented with TPU for a sealing gasket, however this proved excessively challenging and costly, thus its omission

A self-conducted airtightness test is included for reference (water was used, visibility may be limited)

2024.11.30 Update:

• Per user request, an external hygrometer compatible lid has been added, facilitating direct external hygrometer readings without the need for transparent material

External hygrometer integration may compromise sealing; application of Blu-Tack sealant to the joints is recommended

2024-13-03 Update:

• Added additional housing sizes for simultaneous storage of multiple filament spools
• Reinforcement rings incorporated into the original design to mitigate deformation during closure
• Central shaft compatibility for larger housings is pending; future updates will address this
