A tiny box to go around a USB type-A connector breakout board (like these: https://smile.amazon.co.uk/gp/product/B07MM5X2J6). Has a little slot to get some wires out too. Possibly could be improved by using 4 screws for the lid.
Technical
You'll need some small screws - I used two M2.3 x 8mm. Otherwise, print in PLA or material of your choice in usual settings. Does need a little retract, but is not demanding to print.
