Heltec V3 Box

Having found the original box where all the hard work had already been done I decided to tidy up the project to suit my needs:

I resized the antenna hole from 8mm to 6.2mm to accept a standard SMA bulkhead fitting.

I added a hexagonal recess to the antenna hole to stop the SMA bulkhead fitting spinning when unscrewing an antenna.

I moved the separation block 0.6mm closer to the board to stop it sliding back when inserting a USB-C cable.

I added a lip to the long edges of the back and a groove to the long edges of the front to allow them to clip together.

I added a small recess to one end to allow the insertion of a prying tool to get the two parts open again.
