Is it possible for you to share the sketch as it has been removed from the project presentation because of the rules of the website?

Finished the enclosure for the sensor on the battery 2477 (1000mA) :)

To install the sensor on the wall, I recommend 3M adhesive strips (with easy removal)

Some more photos... :)

Thank you very much. Great casing, it is very discret. professional design. congratulations :)

@jeremushka

Thanks. This is actually my first experience in designing sensor housings. I've never done 3D modeling before. A month and a half ago I started watching a video on YouTube on modeling in SolidWorks. With printing on a 3D printer is also my first experience.

How did you produce such a nice result? The text and buttons are very detailed.

Is it SLA printing?

Yes it is an SLA. One day, watching again another video on YouTube about how people make models of characters on such printers(with high detail), at some point I realized that this technology is very well suited for prototyping cases for miniature devices. It is possible to obtain an almost industrial quality of the final product. ...Then I bought it :) ...And I did.

These are attempts to repeat the model on the FDM printer(two different people, on two different printers):

It turns out a very interesting surface, like a soft-touch

[Joerideman]

Nice to see the difference.

Do you solder the components on the PCB by yourself and you launch the whole process in factory? Because soldering such kind of chip ATMEGA328_QFN32 is not that easy or need a microscope i think.

I myself solder pcb. These small 328s are easier and faster to solder than the large 328s. Because you don’t need to solder each contact. Positioning, fixing, heating with a soldering dryer, elimination of excess solder with the help of a soldering iron.

Hello Berk,

Do you still have PCB board available for sales for this project or for the upgraded one with NRF5 ?

In about a week, I will post an updated version of this device. The changes will affect the attachment to the case. And it will be available for purchase.

@berkseo Thank you for your answer :) Good continuation on your nice project.
