This was designed to flush mount the Standard Horizon GX2400 VHF radio to a cutout in the dash up to 1" thick. It started off as a remix but I beefed it up and modified it to the extent that it's practically a completely new design.

It reuses the two 1" machine screws that came with the radio to fasten the mounts to the sides. You will also need two 1/4" x 1.75" machine screw and lock washers to secure the radio to the dash.

I printed using PETG for increase strength to reduce the chance of cracking from the pounding across waves.
