PC104 stacks are commonly used in automation and controls applications which could be a potentially hazardous environment for sensitive electronics

The goal for this project was to create an easily 3D printed, easily modifiable, and fully modular case for a PC104 stack of unknown size.

Design[edit | edit source]

Variables[edit | edit source]

  • Height should be 17mm for a single and 34 for a double height module.
  • Keep the outer clearance above 12.7mm to allow room for mating connectors.
  • Decreasing wall thickness beyond 10mm may compromise mounting holes.
  • The connector holes are stored in an array of an array of parameters. [pins2cablewidth(# pins),cable thickness,side,x offset,y offset]
    • side starts at 0 on the ISA bus side and increments as you rotate counterclockwise.
    • x offset is from bottom left corner of PC104 module (when the side is facing you).
    • y offset is from the center of the case.

Mechanical assembly instructions[edit | edit source]

Remove flashing and push.

Costs[edit | edit source]

Item Quantity Approximate Cost
Plastic ~150 grams per section on average $3.33

Current issues[edit | edit source]

  • Rendering time is excessive!
  • Tab dimensions don't always match on the bottom of the mid section and top
  • Clips don't always fit together perfectly

Possible solutions[edit | edit source]

  • Simply model & lower resolution
  • Fix tab code
  • Increase tolerances on clips
