Kenwood TM-D710GA & Yaesu FT-891 RAM 1" Ball Combo Mount

thingiverse

Kenwood TM-D710GA and FT-891 combo mount for a RAM 1" ball. The added support under the 891 is necessary as the 891 only has one screw mount and without the added support the head unit just spins. Hardware you will need. 891 Mount - (Qty 1) M5x12 with lock washer & flat washer 891 Shelf Support - (Qty 2) #8-32 x 1.25" screws with lock washer and nut D710 Mount - (Qty 4) M3x12 with lock washer & flat washer The D710 screws will need some pressure to grab the first couple of turns since the D710 screw holes are not threaded. I noticed on some of the other 1" B RAM mount balls designs, the connecting cylinder to the base wasn't very beefy and others had complaints about it breaking. I added some support to the base + additional girth to the cylinder support. After you install the support shelf the 891 sits on, push it down towards the D710. The fit is tight on the back of the 891 to get the mounting hole to line up. You might want to install the shelf so it's just snug, install the 891 and then tighten up the shelf bolts. I suggest printing this in PETG to survive the heat of the inside of your car. If you leave it in your car in the summer and print it with PLA, the RAM mount ball will fail.
