I designed this because the JX Pro's handle would always wobble when set down flat and I didn't like how much room it would take up when sitting on top of the JX Pro body. Since the handle is curved, I added the cutout near the bottom to make it easier to insert and remove the handle straight up and down (without having to rotate and make room for the handle).
