I needed a holder for my UGreen USB Switch that I could mount to the underside of my laptop stand.

Existing models weren't what I was looking for so I designed my own. Measured the usb switch using calipers and modeled this to spec. It's a snug fit and you'll have to press it in, but it fits like a glove.

The holes are 6.2mm wide, you could insert M6 brass inserts.

When printing, make sure to add supports underneath the mounting holes. The diagonal bit doesn't need to be supported.
