I needed a way to lift my Mac Mini up for better airflow, but wanted it to sit horizontally.
I also didn't have access to a big enough printer for some of the other designs, so remixed @83metoo's model, and cut out the connecting plastic.
You'll need four of these to raise up your Mac.
I used PETG, but other materials such as PLA will be more than sufficient.
The author remixed this model.
