A replacement box for small hardware items bought from Aliexpress.
Put your own text on the name plate and glue to the base. Fit the lid and push a piece of filament into the hole at the back to complete the hinge and trim the ends.
The clip can be a bit tight initially but it will wear in, or you can just scrape a bit off the bump in the lid if you wish.
Size: 130x70x27mm
