The lateral temperature for the Printer-Box enclosure contains a model for a bracket to hold it to the panel. However, this didn't work as the holes were too large to use the plastic to screw into. It also couldn't clear the bottom metal bracket. Using bolts is an option, but I found it too frustrating to get the lower nuts threaded onto the screws.
So I designed a part that would hold the nuts and clear all the obstructions. It was designed around the square nuts supplied by Printer-Box for the enclosure. I recommend using the M3x12 screw to ensure good thread engagement.
