Make a small box for the AQI project

About half a year ago, I made a project of AQI device with Raspberry Pi Pico W and ENS160+AHT21 chips.  I put them on a block of 2X4 wood. Now I have a chance to make a box with my 3D printer. I can also design it on Autodesk Fusion with my limited 3D design experience.

I started the design on the paper first.

Then transfer it to the Fusion software.

I exported it to the 3mf format. Loaded it to the Bambu Studio. Sliced and printed it.

OK, I put the heat inserts for the screws.

I need iron to heat the bronze inserts and push them into the hole. It doesn’t need much push.

I re-soldered the wires. I replaced the old wires with soft, flexible wires.  Add the cover.

The only problem of the design is the distance of the four holes of Pico is not that correct. I am not sure if it is the measurement issue or the printer issue.

But, it is not the problem. I can use two screws for the Pico. One screw for the ENS160 and AHT21 board.

Update: Just found the problem, I used the Pico size instead of Pico W. So there is a little bit of difference.

 

Here is the web report page.
