Modular PC104 Case

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.

• 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.

Remove flashing and push.

• 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

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