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.
