Yaesu FT-857D Side Rails v1.0 by AB3ZI

thingiverse

Two-piece side rails crafted specifically for Yaesu FT-857D and FT-857 mobile radios (also compatible with FT-891). These rails can be mounted on both sides of the radio. Some signs of warping and delamination in PLA were spotted after just a few months of using these radios for mobile operations during the hot summer of 2018, even though steps had been taken to minimize cabin temperature while parking the vehicle.
