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]
|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
