V1.0
Notes:
Assembly consists of separate top and bottom case pieces.
There should be enough room for the Seeeduino, which was not included in the STEP file I used for reference.
Overall footprint of case is 80mm x 80mm x 30mm.

CAD review:
Overall looks great! I like how you fillet all the edges and you added clearance to the bottom of the mount. There are a few things that the step file of the board is missing
I checked out the board in the bay and took a pic (image below). A few noticeable differences to the step file:
There are a few screws that attach some circuit parts to the board; they stick out below the board so make sure they aren’t interfering with the mount
I would double check the Seeeduino connection and make sure there is enough clearance with the top mount
If you’re able to, it’ll be great to have a chance to look at the board and make sure all the circuit connections have enough clearance and won’t interfere with the mount
The thickness of the top mount can be decreased to 5 mm instead of 7.5 mm, just to shorten print time
It would be nice if the sections I highlighted in red were at least 2 mm (around 2 mm thickness around the holes) so that when we print it doesn’t print weak/weird. If you think there will be some interference with any connections because of the change, you can leave it and we can see how it prints
I really like the stand offs for the mount but because the edges already supporting the board, I don’t think we necessary need them (it might just take up more print time)
I’m a little concerned with the clearance of the red section in the image below with the board so I might suggest shortening/cutting the section to line up with the mount height/thickness (if that makes any sense)

V1.1
Notes:
Addressed all the previous issues regarding minor adjustments (removing unnecessary stand-offs, adjusting certain dimensions to make printing easier).
I measured the board in-person and increased the height of the top case which should now fit the Seeeduino.
I increased the height of the bottom case so that there is a clearance of at least 10mm for any screws that are sticking out below the board. I believe this should be enough from what I could tell by looking under the board, though wasn’t able to measure directly.
I increased the spacing slightly between the board and the case walls to allow for any components to have some more clearance horizontally.
Overall footprint of case is 80mm x 80mm x 40mm.

V1.2
Notes:
Bottom case remains largely the same.
The top case no longer covers the seeeduino or the debug header pins directly beside it in order to provide easier access to those pins.
The lid thickness was shortened to 3mm and its height was shortened to bring it closer to the board to allow the ports to be accessed more easily.
A space was made with clearance holes for mounting the display on top of the case.
On top of the case next to the seeeduino is a loop for the antenna to go through and possibly be mounted to. Let me know if the hole clearance for this is not enough. This could also be made into a separate piece instead if desired.
All LEDs included in the .step file now have holes in the case directly above and beside them for easier viewing.
If needed, the cables connected to the servo pins could be zip-tied to the top of the case in case they want to be secured that way.
Overall footprint of case is now 80mm x 80mm x 32mm inclusive of the raised sections on the top case.
