There are many similar brackets around for many different radios but none for the Icom IC-2730, so I made one.
I used cheap M4x8 socket head screw from a kit, they worked nicely but I feel that they are just a bit smaller than the holes on the radio.
I added a fillet on one side because it looks nice!
This was made for the IC-2730E version and will likely fit the A version, but please make sure it does before printing.
I included the .STEP files in case someone wants it.
Update 27/01/2023:
Added .stl file
