When my job "upgraded" our computers to the once-latest and very sub-greatest HP laptops, I noticed my brand new ZBook was at risk of overheating by day 2. The main problem was the half-millimeter of clearance between my desk and the cooling intakes, and the rubber feet only serve to choke airflow further. This was my solution: print some feet to hold the vents upright in the air for maximum airflow. If you just want the airflow, you only need 2 copies of the "Claw" piece and a couple dowel rods to align them. The feet all include a channel that's meant for some wire to tension them into a single rigid structure. If you want to keep the silly hockey-puck "dock" these newer laptops use, then you'll want to print the rest of the parts too. I recommend printing the "Sleeve" piece in a soft TPU so you don't have to sand it down to perfection in order to hold the dock cable securely. The design is supposed to also help you align the cable plug so you don't have to keep guessing blindly at where the USB-C port is on the backside of the device.
