Canon R8/RP GRIP (no battery)
If you have big hands, R8 may be hard to hold only by 3 fingers, esp if you have a heavy lens. To compensate that i quickly made a grip handle to make a place for entire palm. To make it you will need a tripod screw and 2 metallic or plastic pins to prevent the rotation of the grip. It is the first version of tis grip so i'm going to test it in the field and make a second version.
