3D printed housing for DIY dimmer



    The hero of our post today is AlexNZ AlexNZ , art director of the JetStyle company in Yekaterinburg . Alexei not only offered to help develop a case for our dimmer, but also, firstly, he really developed it, secondly, he printed several copies on his printer, and thirdly, he beautifully photographed the result of his work. For which we say many thanks to him today!

    A brief introduction to the course for those who first saw our project
    We are developing a complete Smart Home system. The “first swallow” of our system is a DIY dimmer. Here are its main features:

    • Work on the 2.4 GHz radio channel (own protocol, without licensing restrictions, or ZigBee implementation based on Atmtel BitCloud)
    • Encrypted Connection
    • Installation without changing the standard wiring of an ordinary apartment
    • Low power consumption
    • The familiar appearance of the switches
    • The ability to independently expand both hardware and software functionality
    • Open source software as well as hardware


    If you want to join the discussion of the system features, please read all our previous articles and comments on them. Most likely questions after such familiarization will become much less.

    The work was done in the free Blender package : The



    source is here , but take your time grabbing it and typing in dozens. This is only an alpha version, we still have to pretty much adjust the model. Work with latches, which tend to break, make special holes for the input cable, and so on. The modified model will also be published. In the meantime, all interested people can play in the editor themselves, change something for themselves and print their personal copy.

    The printed case looks like this:



    The base detail was polished using an acetone bath. The estimated weight of the case is about 6 grams. Used Vision "Hometeam" 3d Printer purchased on Kickstarter:

    The case wall thickness is 1mm. A large view of the latches of the housing cover, which in life have not shown themselves very well:

    For those who do not yet have a 3D printer


    We have some good news. To some extent, we will be able to satisfy the demand for such printed cases. And the price tag will be much lower than what was announced in that post with the survey . Details will be announced upon the final revision of the three-dimensional model for printing.
