Magnetic Dry-Box / Storage Container (round 57mm x 20mm)

This compact, cylindrical storage container consists of two halves—a lid and a base—that clamp together magnetically. It’s designed to hold small items securely while allowing gentle airflow through an array of tiny vent holes. Three embedded 5 × 3 mm neodymium magnets in each half create a firm, tool-free seal.

Magnetic Closure

• Three pockets sized Ø 5.25 mm × 3.2 mm deep (clearance +0.25 mm) accommodate 5 × 3 mm magnets

• Evenly spaced at 120° around the perimeter for uniform clamping force

Ventilation Array

• Seven through-holes Ø 2 mm arranged on a Ø 44 mm circle

• Provides gentle air exchange without allowing large particulates in

Fit

• Outer diameter: Ø 57 mm

• Inner lip diameter: Ø 54 mm

• Storage cavity diameter: Ø 44 mm

• Wall thickness: 1.5 mm for strength and rapid heating/cooling

• Total height: 20mm

Magnet Installation:

• After printing, clean out each magnet pocket with a Ø 5 mm drill bit or reamer (if required)

• Press-fit magnets with matching polarities in lid and base (use a drop of super-glue if desired).

• Dry-Box for Desiccants: Store silica-gel packets alongside camera filters, micro-electronics, or small tools.

• Seed or Spice Holder: Keep seeds or spices fresh with gentle air exchange—ideal for gardeners and chefs.

• Hearing-Aid / Electronics Case: Safe carriage for moisture-sensitive devices while allowing controlled airflow.

• Jewelry & Trinket Organizer: Protect rings, earrings, or watch batteries from humidity buildup.

• Field Sample Container: Geologists or biologists can store small rock or insect specimens without airtight trapping.
