DDS Signal Generator Case

thingiverse

I acquired a DDS Signal Generator from a Chinese online store several years ago, and although it was affordable, the device lacked a housing or case. To prevent any potential damage, I decided to design one myself. First, I created a detailed drawing of the generator, which allowed me to use this model as a guide when shaping the box around the device. The six buttons posed a bit of a challenge to incorporate into my design, but ultimately worked out well. I opted for 3mm Plexiglas (PMMA), realizing that any material thinner than 3mm would not accommodate the buttons and would result in them being loose. The case itself is closed and secured using long m3 x 40 mm screws and nuts. While it's true that any screw longer than 33 mm should suffice, I've found that even slightly shorter lengths of 10 mm can still provide sufficient support for the PCB of the generator. To secure the PCB in place, I use M3 screws and a nut. For designing this box, I employed SolidWorks software, which enabled me to create precise dimensions. Additionally, I included a dxf-file, allowing users to easily import it into most laser cutting software for accurate fabrication.
