Nice job! I ordered one of the 3D printed ones, and have briefly used it for the 9.7” iPad. Aside from no angle adjustability, my biggest concern is the additional unplanned for weight is now fully supported by the fragile silver tubes, and the unbalanced weight of the entire setup while holding it during flight, making it fall away from you, stresses the tubes even further. For this reason, I have reverted to the PGYTECH
Mavic 2 tablet holder, mounted backwards into the phone mount, which suspends the iPhone tablet weight over the middle of the RC for a balanced setup, with no additional stress on the silver antenna tubes. A key ring around the base of the vertical bar of the tablet holder allows attaching a lanyard, so it can hang freely vertically, when needing both hands, while still acting as a safety strap during flight, with a quick release clip in the lanyard.

I mount mine flipped 180° from the image below, with the vertical bar coming up at the front side of the plastic base, instead of the far side, next to the antennas. Also, no metal near the antennas that way, too! Base is all plastic.
