Based on the Modular Desk Clamp system by hein, this will let you hang a 14" MacBook Pro off the edge of your desk (if you dare). It's reversible and exposes all of the ports, so you can insert the computer from either end. It also allows for airflow through the side vents.
Currently, you need to print with supports – I had good luck with tree supports on build plate only. If there's interest, I might add a version with 2 hooks and versions that attach the hook using M3 screws/nuts instead of being attached directly to the model.
The author remixed this model.
This uses the mounting system created by hein. It will hold a 14" MacBook Pro.
