This first batch was developed as part of Active / Passive Vol 5. as an interactive workshop. These units are branded "Active Passive" on the ground shield, and are a limited run. We learned a lot from the workshop and reworked the 3d printed case to make for easier assembly.
Files are available at the CCTV Github, ready for modifications, repairs, and opening up the possibility of modifying the case design to suit your needs.
