3D Printing

The PiTrac enclosure components require 3D printing. The 3D models and printing instructions are available in the main PiTrac repository.

3D Models Location

All 3D printable parts can be found in the main PiTrac GitHub repository under:

  • 3D Printed Parts/ directory

Printing Requirements

  • Printer bed size: Designed for small-bed 3D printers (such as those available at public libraries)
  • Material: PLA recommended
  • Print time: Multi-day project due to part sizes
  • Assembly: Some parts require post-processing and fitting

Enclosure Versions

Version 1 (Original)

  • Bulky design
  • Houses all OTS (off-the-shelf) parts and separate Pi SBCs
  • May not work for larger power adapters (like U.K. bricks)

Version 2 (Current)

  • More streamlined design
  • Two variants:
    1. Compute Board variant: For future integrated compute board
    2. Connector Board variant: For current OTS parts build

Refer to the individual part files for specific print settings. Generally:

  • Standard resolution should be sufficient
  • Support material may be required for some parts
  • Pay attention to part orientation for optimal strength

Post-Processing

  • Remove printing supports carefully
  • Test fit before final assembly
  • Sand contact surfaces if needed (especially lap joints)
  • Some parts may require drilling or trimming for proper fit

For detailed printing and assembly instructions, see the Assembly Guide.
