DSO138 Oscilloscope case with 9V battery and a power switch

thingiverse

This is an adaptation of the case for DSO138 oscilloscope that features a 9V battery and a rocker switch for power - no tumbler switches allowed. Soldering was a breeze, as evident from the pictures. If you have any questions, feel free to ask. I simply used leads from one of the power jacks to get it done. Here are some areas that can be improved: * The hole for the rocker switch was a bit too tight, so I had to file it down slightly. Feel free to increase the buttonHole parameter in the scad file. * The USB hole is misaligned - it's shifted upwards. This is a problem with the original design I remixed. If you need it corrected, move it down or expand it. * The battery compartment had some extra space, so the battery could rattle around when shaken. To fix this, I placed the battery on a piece of cardboard. Alternatively, you can modify the design to include a plastic "bed" for the battery. * This is also an issue with the original design, but not all screws gripped properly for me. Some were loose and barely holding in place. Decreasing the hole radius may be a good idea, especially if your printer has tight tolerances.
