This dock is designed to be used with a Macbook Air to extend storage capacity as well as dock capabilities, using the MINIX NEO Storage, 480GB Aluminum USB-C Multiport SSD Storage Hub and a 180 deg USB C adapter, and (optionally) something to attach it to the bottom of the laptop. (links to all below).

You insert the storage hub into the dock, fasten it to the underside of your laptop (or just place it under there if you prefer) and use the 180 USB C adapter to connect to the laptop.
It then gives just a little bit of tilt to your laptop to raise the screen and potentially increase typing comfort (but that's a personal preference thing).

I've tried to add some venting to this design, but the hub can get a little warm. Also, if you leave the hub plugged in all the time, it will drain your battery faster. Use at your own risk. It may cause the hub to overheat, although I haven't found that to be the case as of yet.
