For pilots and others building their own ADS-B receiver using the Raspbery Pi based Stratux project, here is a popular case designed by Helno. See more about the design and the designer here: http://www.thingiverse.com/thing:1016829.
Makers can print these on demand as needed with no markup; after ordering my own, I made it available for others to do the same (I make no profit).
This is the TOP ONLY - you will also need to order the base to have a complete case. See the Stratux project page for assembly directions.
Directions:
1. Select the material you want. I recommend Strong and Flexible Polished (similar to ABS). Any metalic materials or finishes may impact reception, especially the GPS module (if installed).
2. Select your color
3. Press order
4. Assemble and Fly!
NOTE: The order page displays a caution about this part because the material thinkness in some areas gets thinner than they happy with. Notably this impacts the thickness of plastic underneath the mounts for the GPS/AHRS module - as long as you use short enough screws you will be fine. Also some of the corners of the logo on ths top are a concern for their guidelines.
