Storage & Organization

When ordering components in bulk (to reduce cost), a proper storage system becomes essential. The repository includes parametric 3D models for a stackable PCB storage system:

  • Window display: See all stored components at a glance
  • Stackable design: Compact vertical storage for many components
  • Parametric sizing: Customize dimensions via CAD variables:
    • int_width: number of columns
    • int_length: storage container length
    • int_multiplier: PCB width scaling (1 or 2)

Print multiple storage bins and stack them to easily organize and access your entire component library. This is particularly useful for classroom settings where sets need to be sorted and quickly retrieved.

See the PCB-storage-system folder in the repository for complete design files.
