Enclosure & Case

The IARC v3 case holds the OPS243-A, the sound sensor, the angle radar, the monitor, and the Raspberry Pi in one printed assembly.

STL, STEP, and 3MF files live in cad/IARC_case/ in the repository.

Fasteners: 10 × M5 bolts, 12 × M2.5 bolts.

K-LD7 mounts are for deprecated hardware

The KLD7 mounts in this case are for the deprecated K-LD7 angle radars. OpenFlight has moved to the TI IWR6843. Skip the KLD7 mount steps for a new build.

The assembled IARC v3 case

Assembly

  1. Print out sensor_housing.stl
  2. Print out (2x) OPS_mount.stl
  3. Secure the OPS sensor to each OPS_mount.stl part with screws (I don't know which ones)
  4. Secure the OPS_mount.stl parts to the sensor_housing.stl part with (2x) M5 bolt
  5. Fit the sound sensor into the little slot on the left side of the sensor_housing.stl part.
  6. Print out (1x) KLD7_h_mount_L_v2.stl and (1x) KLD7_h_mount_R_v2.stl
  7. Slot a KLD7 sensor between the mount parts, and secure them to the sensor_housing.stl part with (2x) M5 bolt
  8. Print out (1x) KLD7_v_mount_L_v2.stl and (1x) KLD7_v_mount_R_v2.stl
  9. Slot a KLD7 sensor between the mount parts, and secure them to the sensor_housing.stl part with (2x) M5 bolt
  10. Print out the monitor_mount.stl part.
  11. Print out (4x) monitor_standoffs.stl's.
  12. Secure each monitor_standoff.stl part to the corners of the monitor_mount.stl part with (1x) M2.5 bolt.
  13. Secure the monitor to the monitor_mount.stl part.
  14. Secure the raspberry Pi to the monitor.
  15. Print out the monitor_shell.stl part. If you use the Raspberry Pi Touch Display 2 instead of the 7" HMTECH touchscreen, print Touch_Display2_shell.stl and Touch_Display2_backplate.stl instead.
  16. Secure the monitor assembly inside the monitor_shell.stl part with (4x) M2.5 bolts at the corners.
  17. Print out the monitor_back.stl part.
  18. Secure the monitor_back.stl part to the monitor_standoffs.stl parts with (4x) M2.5 bolts.
  19. Slide the whole assembly into the sensor housing assembly, using the dovetails to align everything together.
  20. Print out the name_plate.stl file.
  21. Secure the name_plate.stl file to the front of the whole assembly with glue.
  22. Print out the curvy_backplate.stl file.
  23. Secure the curvy_backplate.stl file to the whole assembly with (4x) M2.5 bolts.
  24. Print out (4x) case_foot.stl parts.
  25. Secure each foot to the bottom of the whole assembly with (4x) M5 Bolts.

And that’s how you put together the 3d printed parts!
