Print Settings
The PETG print in the photos used 0.2mm layers, 15% cubic infill, 2 perimeters, and manually painted supports under the hook.
Usage Tips
The broad, flat back surface supports both command strips and magnets. Since the magnets are inserted from the TRMNL side, there's a layer of plastic protecting the mounting surface from any scratches or damage from the magnets. I used a single 20x2mm neodymium magnet in each corner; you can stack multiple magnets or use thicker ones (e.g. 20x3mm) for more security.
When mounted, the button is just left of the TRMNL logo on the bezel; press there (inwards towards the mounting surface) to activate the button.
To optionally lock the TRMNL onto the hook, put the small printed lock insert or another small object into the slot in the back.
To optionally strengthen the hook and prevent layer separation, insert a 2.5mm flathead screw into the countersunk hole in the back. (Even if you don't do this, the perimeters around the hole itself help strengthen the hook.)
Caveats
The exact tolerances of the press-fit parts, such as magnets and the lock insert, will depend on your printer, your filament, etc. Customize the included Fusion360 model to fit your needs, or adjust sizing in your slicer to optimize the fit.
You can also insert another object into the lock slot. I actually ended up using a folded piece of paper towel!
