This is my take on the ground skimmer / bolted frisbee / ground tripod. I have full confidence in this rig, with my biggest lens, down to my smallest. When I need to work on my belly, waiting for that perfect moment, this will save my arms the shakin' and achin' of holding up a 9lb rig. I hope someone else can use it too! The commercial options were all too expensive for my taste, so I designed this.

The size is restrained in order to fit on any bed at least 200x200mm, or 200mm diameter. The first layer goes down with a diameter of 187mm, and the skimmer is 195mm diameter at the top. Almost anyone with a standard reprap or above should be able to print this.
