Ryobi 18V Lawn Mower Battery Holder

I designed the clamp in two pieces. One part screws onto the battery plate with three 4mm flat head screws and the second part screws to it clamping the assembly to the handle. I used 4mm threaded brass inserts in the block.

This remix fits the 13" P1108VNM lawn mower with the 19mm tubular handle. I separated the battery holder and added 4mm flat head screw holes.
