Linknlink eMotion - Ultimate Fixing Solutions, inc. Directional Faraday Cage (allowing eMotion to work with fans and AC's in the room)

This repo is for everyone. 

I designed pretty much all fixing scenarios you might need, however, if you think there is something I missed, please let me know. 
It is a modular design, you can choose whether you want fixed 90-degree angle, or ball joint moving 45dg in each direction, or direct fixing to the wall, with cage, or without.
You don't need to print everything, just choose what you plan to use… (plates info below)

See the assembly video:
 

PRINT INFO:
- DO NOT print with nozzles bigger than 0.4mm! Only 0.4mm or less.
- I recommend printing by object, not by layer.
- I'm providing full 3mf file with plates, so it's easier for you to orient. See the screenshot in gallery. 

GUIDE ON HOW TO CHOOSE BETWEEN PLATES:

• PLATE 1 (Print only if you want to use the Faraday cage)
  - You'll need both big parts (main body + cover)
  - If you want adjustable ball joint then print also part in bottom right
      - choose ball female part from plate 4 if you want to use with the stand
      - choose ball female part from plate 2 or 3 if you want to use with the wall plate (or if            you want a bigger wall offset, you can still use longer part from plate 4)
  - If you want straight 90º connection, choose one of the two parts in top left corner
      - longer is for stand
      - shorter is for direct wall fitting (choose 3mm or 4mm base from plates 2 or 3 with it)
   
• PLATE 2 - Direct to the wall fixing (4 mm screw or 30 mm rounded 3M tape)
  - Top row: Print for ball joint adjustable tilting option
  - Middle row: Print for 90 degree fit with slight offset from the wall (~12 mm)
  - Bottom row: Print for 90 degree fit with no offset from the wall
   
• PLATE 3 - Direct to the wall fixing (3 mm screw or 30 mm rounded 3M tape)
  - Top row: Print for ball joint adjustable tilting option
  - Middle row: Print for 90 degree fit with slight offset from the wall (~12 mm)
  - Bottom row: Print for 90 degree fit with no offset from the wall
   
• PLATE 4 - 10 mm slide ins
  - Top row: Ball joint
  - Bottom row: 90 degree
  NOTES:
      - These are primarily for the stand, but if you want more offset you can use them with base from plate 2 or 3.
      - You can also create your own part that connects to your specific furniture. You just need to implement a hole with DIA 14 mm and depth 10mm, so my slide-ins will fit. I'll post an example of bespoke adapter later.
   
• PLATE 5 - The stand
  - As all plates, it should be printed as is oriented, no support needed. Seams in the back.
  
  
      

MY SETUP (for reference):
Creality K1, 0.4 nozzle, Orca Slicer, 3 walls, 3 shells, Infill: 10% gyroid, JAYO PLA+

FARADAY CAGE OPTION INFO:
- Full disclaimer: I own several eMotions Pro, not Ultra variants. I know that ultra has an option to set "Interference zones" as Aqara FP2. Given I do not own Ultra, I can't tell how well these zones work. I'll be happy to hear from you... My "Directional Faraday Cage" option might help even to people with Ultra models, however, what I can tell for sure it is a Godsend for people with Pro model.
- Compatible detection mode: “Wall-mounted (short-range)”, with this mode the cage is working perfectly, not tested with any other.


- WHAT HAPPENED TO ME: I installed eMotion Pro in my son's room, it worked pretty well... until it did not. As soon as my son turned his tower fan on, it stayed in "occupied" state forever... Despite I had the fan in mind during install - eMotion was installed ~1 meter away from the fan, and fan was slightly behind eMotion. Nothing helped.
- That's the reason why I developed this fixing solution. I can attest it is working 100%.
- All you need is my print file and a piece of kitchen aluminum foil. The foil does the shielding, and it's hidden inside the print.

How much foil do you need and how to calculate it???
- It depends on its thickness. A standard cheap foil you can get in e.g. Lidl is pretty thin. From my experience, you need approx 6 layers. The easiest way is to test it for yourself like this:
LAYERS TEST
1) Place a paired, operational eMotion horizontally on a flat surface.
2) Take a larger (~40x40cm) piece of foil and fold it twice. This gives you 4 layers of ~20x20cm shielding material
3) Place it on top of the eMotion, tuck the edges so it covers the front and sides too (!important) and check HA or LnL app if you ever get "not_detected" state when you are next to it.
4) With 4 layers it is unlikely to happen, but wait approx 1 minute, just to be sure.
5) If within a minute you won't get "not_detected" state, add 1 more layer and wait ~1 minute again while standing next to it.
6) Repeat until you see "not_detected" state, and remember number of layers as number "X".

INSTALLATION:
- Shielding material is installed on this cover part:
- The wall height is 24.75mm, so let's add some excess and round it up to 30mm. Fold a new piece of foil every 30mm as many times as your number "X" is, and add 1 more for safety → Cut it, so you're left with one 30mm strip folded "X+1" times.
- Now, wrap this 30mm strip around printed part.
- You may cut the LENGTH excess (just leave a small overlap)
- You must cut the HEIGHT excess, the easiest way to do it is with a nail scissors.
- Insert "Cover shielding part" into the "Main body part", and you're DONE!

NOTES: 
- If you want to use this "Faraday Cage Setup Option" with eMotion Ultra, you might need more layers because it has 60Ghz radar. With Pro model sufficient number of layers should be within 5-10 range.
- Make sure you set it up either on highest sensitivity, or the sensitivity level that you are planning on using.

ANY ISSUES:
- Please, remember, every 3D Printer is a bit different, if you have any problem with clearances, do let me know. I will provide scaled options based on feedback in comments section.
- You can also try scale it yourself in slicer, but I don't recommend this, it's better to let me know. I will send you updated version based on your needs quickly... With that said, try to print something smaller first, so you can check your clearances. 
- Remember, if some part is a bit bigger for you, just use a sandpaper.

ANY QUESTIONS:
- Leave a comment. I'll reply.

Have fun
