DDS Signal Generator Case

I bought some time ago a DDS Signal Generator in a Chinese web shop. I was cheap but had no housing or case. In order not to damage the device, I decided to make one myself.

I have drawn first the generator, so I could use this model to shape the box around the device. The 6 buttons were a bit tricky to design, but I worked out fine. I used 3mm Plexiglass, PMMA. You need 3 mm thick material else the buttons won't fit and are to lose. The case is closed and held together with long m3 x 40 mm s
