Labrador Electronics Lab Case

thingiverse

This is a case for the Labrador USB device, which offers an oscilloscope, signal generator, multi-meter and much more. The actual device can be obtained from espotek.com, while the software is maintained on GitHub.com/EspoTek. The board as delivered is remarkably small and ideal as a breadboard device. However, I desired a device that could fit in my desk and be easily pulled out to examine a signal without having to set up my 10kg Tektronix scope. So, I created something that would enable me to hold a 70x90cm prototype board and mount some BNC connectors. The BNC connectors were purchased on eBay with the item number 111223480693. Others may also work, but my box was designed around this one. The 80x90 prototype board is available from multiple sources. I obtained mine on Amazon. I have included two "lids" - one has labels embossed on it while the other one is blank. I did not expose all the functionality of the Labrador so you might make different choices. You can add your own labels with Tinkercad or use a label maker in the old-fashioned way. I used supports on the lid with the writing because I printed it face up. It's unclear if that was necessary. Make sure your retraction settings are optimized as the writing can get stringing, requiring you to clean it up with a razor blade. The screws are just M3 and the holes are pre-tapped. I would run the screw in anyway to break in the threads. Note that some corners of the prototype board were snipped off to allow it to fit. If I was doing this again, I would probably take more off as it can make the screws difficult to thread.
