I printed it off and used a SanDisk Ultra Fit USB to fit here. (https://www.amazon.com/gp/product/B01GK9921C)
I had to remove the backing using a pair of pliars and glue the small board in place as it was sliding freely. Once complete I bent the metal casing slightly and it fit nicely- a dab of super glue held it in.
It has been plugged into my computer for about 2 hours now and although it heats up from use it doesn't appear to be hot enough to damage the PLA filament I used.
