Designed to allow the Dragon Link V3 Slim to attach like any other JR Module. The images are of it attached to my 9XR but it should attach to any other JR compatible TX. Can be Printed in 2 parts or one your choice. I printed it in 2 parts then used a soldering iron to weld them together. Good Luck!
Sorry the print in the images are bad. My PLA was not stored right and absorbed moisture.
