I created this Gridfinity bin which has the following features:

• Anker A7516 USB hub slot, with cable going out the back
• Cable channel to tidy up USB cables coming from behind my desk
• USB drive (A and C) sockets and micro SD card sockets
• Slide in magnet slots which don't require glue (3mf only)

I've included the fusion360 file in case you wanted to remix or adjust things.
