I'll admit it's virtually impossible to find STL files for Autel drones. I found an STL for the landing gear I need, but not the antenna frame that goes inside it so I've spent the last two months learning CAD and trying to make my own. On the other hand, I think you'd be surprised. I bought my first 3D printer in January and I was shocked at how big the community is. I am restoring a 1974 Mercedes 240 Diesel in my spare time and being able to print hard to find parts paid for my $400 printer in the first 2 weeks. Even if you don't have direct access to a printer, you can email your STL files to hundred of companies who will print it for a small fee. When you have a company like Autel that doesn't sell parts to the general public the value of 3D printing is priceless.
