    On corners i used brass pipe. walls - 1mm brass sheet.

    all part was soldered using simple iron, or you can use dremel versatip photo of casing from top

    casing with laser-cutted acrylic glass (if you'll interesting - i have glass drowing)

    on this photo youll see how parts was soldered

    and just assembled casing without bracelett ears

    box-style design

    folding and soldering. Button-style charging port

    PS. is you'll need worklog - i think ill make one in a few weeks
