I know that there are multiple ways to attached the access panels on the wings. Glue them in, clear tape, and etc. I made these screw on plates to hold them on, incase I need to remove the access panel. The download is enough to support one wing so you would have to print it twice. The screws are plastic/nylon 6-32 bought at your local hardware store same as the 6-32 nuts that snap into the inside plate. I did make these for the RVJET but could be modified for any wing.
