Modified chassis for jetbot

I have modified the standard chassis for Nvidia's Jetbot so that I can use the WiFi module on M2 slot of the 4GB Jetson Nano card.
The modification involves the addition of two housings for M3 threaded inserts, to be hot inserted, and a support plate for the two antennas to be mounted using two M3 screws.

I am also attaching the 3D model of the frame in step format obtained by reworking the original in stl format.
