Fluke Scopemeter IR Transceiver

Case for adapter board for the optical port of fluke scopemeters.
I have no schematics of the PCB, but it's just an IR Led + IR Phototransistor connected to a USB - UART converter.
Screws to connect lid to bottom are M3 screws.
A software for this can be found on my github : https://github.com/simpre/flukereader
It's important to print it with the connector facing downwards as the connector has not the same size when printing laying flat on the floor of the case.
