I didn't find the back part of the Nazgul Evoque properly 3D modeled on the internet for additional GPS module, so I designed an almost exact replica of the part where the XT60 and the video antenna are and extended it for the HGLRC M100 GPS module (both files are attached). Feel free to modify it for your own GPS module!
I printed the part using TPU, which I would recommend you do too, because it's more crash resistant and the original was also made from TPU.
If you also mount the HGLRC M100 GPS module using my 3D model, keep in mind to fly carefully because the module isn't mounted too firmly.
The author marked this model as their own original creation.
