I haven't tested this out yet but I will soon, I think it'll work better than the factory mount plate and will be much cheaper too since they don't sell them individually.
I printed mine with PETG and supports are recommended.
The author remixed this model.
The mount is the same as DaHouzKat's design, the rest of the plate is thicker and the wall mount points are further apart so they can't interfere with the Airmini's mount and use standard hardware.
Post your makes if you like!
