The file 'Heltec Lora SMA Antenna With Hex To Lock Ipex To SMA From Turning And Hole For Lanyard. 3D Printer Model' is (stl) file type, size is 32.2KB.
I have modified the original design of the case to add an area to lock the SMA connector from rotating (an issue I had) when unscrewing the antenna.
I also added a hole for a lanyard.
The hole for the SMA adapter is a tight fit and will require using a screwdriver or pick to push the connector into place and use the nut to pull the connector in the remainder of the way.
