What it does
- Leaves the Mac's base open. The M4 and M5 Mac mini draw air in through the bottom. The cradle holds the Mac by its edges, so nothing sits under the vent.
- Keeps the power button in reach. The button is on the underside near the back. With the floor open you reach it from below.
- Holds the Mac with a front ridge. It slides in, drops behind a small ridge and stays put. Lift the front a millimetre or two to take it out.
- Prints in one piece with no supports. It is printed standing on its front face, so the Mac's weight runs along the printed layers, not across them.
- Comes with a 1:1 drilling template and a 50 mm check bar, so the four screws land where they should.
How it is being tested
The shape came out of structural simulation (how far the walls open under load, what each screw carries) and airflow simulation (how much of its own warm exhaust the Mac breathes back in). The guide Mac mini under a desk: does it run hotter? explains what the airflow work found.
Simulation is not a test. Before anything is sold, a printed cradle gets a physical hang test, and a Mac mini runs a 20-minute load in it and on a desk, logging chip temperature and fan speed. I will publish both results on this page. Until then there is no load rating here, on purpose.
Two versions
