This is a two port USB extension bracket for mounting under a desk or table. It was designed for Amazon Basics USB extension cables but might fit other brands.

It was designed to use 4 screws for mounting. The screw holes have a diameter of 4mm. I used self-drilling screws to mount mine. If you don't wish to use screws some good two-sided tape might work as well.

If you have tuned bridge settings this will print without needing supports.
