Great concept. I have a few questions:
What is the material used?
Is it 3D printed? (I ask because you can see the raster lines in the video, but could be a prototype of the final product) For mass production would a different manufacturing technique be cheaper/more efficient? Think injection molds.
What is the individual weight for each, cell and mount?
Why such a large fastener size? Why not provide a #6 (or similar) clearance hole as a pilot if teams need to use something larger. For the weight of the components, a 1/4" screw is way overkill. In the game of pounds, ounces matter.
