I have a solution that makes the iPad Mini 6 or iPad Mini 7 work well. I do not have a 3D printer so I also don’t have the means to share a file with those who do.

It is high enough to not block view of radio frequencies and can be positioned low enough to not interfere with canopy.
I connect the iPad to a Stratus 2 (Wi-Fi) to be an independent backup system to the Garmin. I also connect the iPad (Bluetooth) to the G3X for ease of sending flight plans back and forth. Works great.
The piece "hangs" on the egress assist handle and the lower part rests against the panel. A piece of 1/2" rubber on top utilizes the canopy frame to hold the mount firm on the handle. Can't bounce out in turbulence and can't even move or shake around in flight with canopy closed. Getting in or out is easy as the piece simply lifts off the handle when needed.
