USB Blocker Permanent
thingiverse
Yet another USB blocker, permanent type. Made with OpenSCAD, so you can modify it. By default blocks USB hole 6mm * 13.4mm with 1.5mm hole depth. It has a 0.5mm bezel at the bottom to prevent push through. Really fiddly to print just one, recommend PETG with proper bed levelling and first layer adhesion.
