Rugged Case for LowPowerLab CurrentRanger

This is a rugged case for holding the LowPowerLab's CurrentRanger precision ammeter, along with two 18650 batteries for power and some accessory cables. The case is designed to have the CurrentRanger mounted in it, as the CurrentRanger is just a circuit board without any sort of case of its own. Below the board is a compartment for a pair of 18650 Li-ion batteries (in parallel not series), plus some room for foam packing material, that will allow the device to run for many many hours without being plugged in. The top has a panel that some soft 5-10mm foam can be glued to to pack nicely against the CurrentRanger's Oled display to prevent it from coming unplugged and bouncing around inside the case. Behind the panel is another compartment for storing whatever you want, I have a USB-C cable and a banana jack to BNC cable for using the CurrentRanger with an ocsilloscope. There's a DXF file included for the foam piece if you have a laser cutter, but you can also just cut it by h
