Final CAD touches.

Wow. That went quick.

This is the final cad entry though.

First things first, I had to split the casing into two sections that would fit on my printer. These sections would be joined with M3 bolts and heat set inserts.

This is a simple overlapping butt joint with 4 screws per side. Nothing complex, was just a few sketch and extrudes.

Next was building up interior structure, which you can see part of in that screenshot. I basically just needed mounting for the screen and board.

This is what I came up with. I also added the port cuouts on the side while I was at it.

This one interior strucutre has mounting holes for both the screen and the lattepanda carrier PCB.

Here is the other side. Unfortunately, this will need supports to print, as I couldn’t think of a way to avoid them, which hurts me. But it is what it is, I will make do.

Here is the interior with the components. Looks good!

Lastly, I added 4 antennas. That’s right, 4.

One is on the inside in this corner!

The square one internally is a GPS antenna. It is a ceramic active patch antenna. The other 3 antennas are simple “rubber ducky” antennas for Wifi+Bluetooth and LORAWAN. Short and simple.

That’s it for cad! Now I just need to take renders and put the repo together with a BOM and stuff!

Wait, I forgot screws.

Now we good. I also added slits to the back for cooling! They will just be lasercut into the aluminum.

Okay, alll done for real this time. Now we move on to renders and stuff.
