OpenBeam
Stacking parts
Most common material cut in a US hackerspace is 3mm thick. 1/8" acrylic is nominally .118", or 3mm. Same for Baltic Birch.
Therefore, one can stack 5 pieces together to form a solid shape that will stack evenly against an OpenBeam 1515 extrusion. In this example, we formed a shoulder stock for a DSLR video rig this way. This shoulder stock can also telescopic forward and backwards on the rail for fine adjustment.
