SummaryI did not design this. These are the official 3d printable files for the Astro Pi flight case as provided by raspberrypi.org See this link for more info: https://www.raspberrypi.org/blog/astro-pi-3d-print-your-own-flight-case/ Version 1 Sections 1-4 will work for the Raspberry Pi 2B/B+. Version 2 Sections 2+3 will work for the Raspberry Pi 3, but still uses Sections 1+4 from version 1.
