Didn't like the idea of removing screws to mount the O3 air unit into a tpu mount adapter so I designed this case for the unit to sit on, it has 20x20mm and 30x30mm mounting holes, a channel to run wires under and a couple of braces that hold the unit.
Print without supports, most printers should be able to print ok-ish the bridges
Used 5mm (ish) M2 screws to mount it, 2mm for the carbon and 3mm that go into the mount itself, wholes are pretty tight to ensure it is somewhat securely screwed, also used a couple if M3 screws just in case.
