This is a compact case which I used to enclose an RJ45 female breakout and a 15x20 pin protoboard. I used this to attach a NodeMCU inline on a CAT5 cable, allowing me to inspect some of the pins and send signals while allowing passthrough of the signals from the female breakout.
The case includes a lid which snaps into place nicely with PLA. I used a dot of hot glue to keep the RJ45 female breakout in-place, and the diameter of the cable port roughly gives some strain relief for the CAT5 cable I used.
I printed this at 0.3mm layer height and a 0.6mm nozzle size in PLA, it took about an hour at 150% print speed (default PrusaSlicer settings for my MK3S)
