+# SuperSensor 2.x Case
+
+This is a 3D-printable case for the SuperSensor 2.x all-in-one voice, motion,
+presence, temperature/humidity/air quality, and light sensor.
+
+This case provides a convenient way to cover up the SuperSensor's PCB, either
+for aesthetics or to help protect it from harsh environments.
+
+You can [tinker the design on TinkerCAD here](https://www.tinkercad.com/things/1HT3fyNbln0-supersensor-case).
+
+## Printing
+
+Provided here are 5 `.obj` CAD files designed for slicing and printing with
+any slicer software and 3D printer.
+
+### `body.obj`
+
+This is the main body of the case which houses the PCB. It includes an opening
+for the insertion of a USB-C cable of "normal" size, which should fit most cables.
+
+This part should be printed in a solid, durable material of any colour you wish.
+
+### `face.obj`
+
+This is the front face of the case. It clips into the body with 4 triangular
+grip clips, and has 5 openings:
+  * A large rectangle for the insert below.
+  * A large circle for the PIR and am312 extension tube below.
+  * A small flush hole for the TSL2591 light sensor.
+  * A small funneled hole for the SGP41 air quality sensor.
+  * A small funneled hole for the SHT45 temperature/humidity sensor.
+
+**NOTE**: This design can affect the baseline readings of these sensors!
+Specifically, the TSL will report much lower ambient light levels (up to 30 lux)
+unless light is directly facing it; and the SHT45 will hover about 6 degrees
+higher than the exposed PCB would from my testing. Take these into account in
+your usage!
+
+This part should be printed in a solid, durable material of any colour you wish.
+
+### `insert.obj`
+
+This insert fits into the large rectangle in the face, and provides a diffuser
+for the feedback/status LEDs, including an opening for the INA microphone. It
+is inserted into the face separately during assembly, though a multi-material
+printer could concievably print it into the face during printing.
+
+This part should be printed in a solid, durable material in **a natural or transluscent** colour (it must let light through).
+
+### `am312-tube.obj`
+
+This round tube provides additional buffering for the AM312 over the face, extending
+it by 8mm to completely cover the AM312 body. It attaches to the face over the large
+circular hol separately during assembly.
+
+This part should be printed in a solid, durable material in any colour you wish.
+
+### `usb-extension.obj` (optional)
+
+This square tube provides additional coverage of the USB cable opening for situations
+where that may be needed, either for "weatherproofing", cable management, or mounting.
+It attaches over the opening in the body and should fit most cables. Note that USB
+insertion may be harder with this on so consider that carefully during cable selection;
+a long boot cable is a plus here.
+
+This part should be printed in a solid, durable material in any colour you wish.
+
+## Assembly
+
+To begin, print the parts above as indicated; default slicer settings should be sufficient.
+We will exclude the USB cable opening extension for this assembly, but its installation
+is straightforward.
+
+1. Lay out the parts; you will need:
+
+    * The body, face, insert, and AM312 tube parts.
+    * Superglue
+    * A toothpick (if not using a precision superglue applicator)
+    * A hard, flat surface (I use a vice)
+
+   ![Parts](.images/parts.jpg)
+
+2. Place the face face-down (clips up), and place dabs of superglue at the corners of the
+   insert openings.
+
+   ![Face Assembly 1](.images/face-assembly-1.jpg)
+
+3. Spread the superglue along the inner edges with the toothpick; or, combine 2+3 by using
+   a precision superglue applicator. You need very little glue here; avoid extra ooze!
+
+   ![Face Assembly 2](.images/face-assembly-2.jpg)
+
+4. Firmly place the insert face-down into the hole; the overlap edges should match.
+
+   ![Face Assembly 3](.images/face-assembly-3.jpg)
+
+5. Apply firm pressure to both sides of the insert with your thumbs, a vice, or another
+   pressing object, until the glue can set up (15-30 seconds).
+
+   ![Face Assembly 4](.images/face-assembly-4.jpg)
+
+6. Flip over the face; the insert should now be solidly affixed. Clean up any oozing superglue
+   with a paper towel or lint-free rag.
+
+   ![Face Assembly 5](.images/face-assembly-5.jpg)
+
+7. Place a small amount of superglue on your toothpick tip; if using a precision superglue
+   applicator, skip this step.
+
+   ![Face Assembly 6](.images/face-assembly-6.jpg)
+
+8. Gently spread the superglue around the circular opening (or apply using a precision superglue
+   applicator); you want the bead to be no more than 1mm wide to avoid ooze.
+
+   ![Face Assembly 7](.images/face-assembly-7.jpg)
+
+9. Line up the AM312 tube, and firmly press it down to seal. Clean up any oozing superglue
+   with a paper towel or lint-free rag.
+
+   ![Assmbly 8](.images/face-assembly-8.jpg)
+
+   You will now have a completed face assembly and are ready to install the actual SuperSensor.
+
+   ![Completed Face](.images/completed-face.jpg)
+
+10. Gently insert the SuperSensor board into the case body, lining it up with the four standoffs.
+    Gently press down until the ESP32 is firmly sitting on the bottom (it should require no force).
+
+   ![Body Assembly 1](.images/body-assembly-1.jpg)
+
+   You can verify that the USB plug is sitting flush on the base.
+
+   ![Body Assembly 2](.images/body-assembly-2.jpg)
+
+11. Remove the top cap of the AM312.
+
+12. Place the face over the AM312.
+
+   ![Body Assembly 3](.images/body-assembly-3.jpg)
+
+13. Line up the clips on one side (I prefer the left). Then using a gentle squeezing motion, apply
+    pressur eto the sides of the case on the right side while also applying lateral pressure on
+    the face towards the inserted clips. This picture is a one-handed demonstration, applying a
+    squeezing pressure between my thumb and middle finger and a downwards pressure with my index
+    finger to provide force; using two hands is advised.
+
+   ![Body Assembly 4](.images/body-assembly-4.jpg)
+
+14. While doing the previous step, ensure that the 3 sensor holes are lined up with their corresponding sensors.
+
+   ![Body Assembly 5](.images/body-assembly-5.jpg)
+
+15. Press the face into the body so that all 4 clips are making contact.
+
+   ![Body Assembly 6](.images/body-assembly-6.jpg)
+
+16. Reinstall the top cap of the AM312; it should have a snug fit against the tube.
+
+You now have an assembled case!
+
+![Completed Case](.images/completed-case.jpg)
+
+As a further step, consider placing a line of tape around the face-body joint. The locking clip
+design was made with printing in mind, and does have some play here.
