The laser cut parts turn out to have a bit of wobble when assembled. It doesn't affect gameplay much, but it's a bit disorienting. I'm send a prototype to an evaluator, and am considering solutions.
RE-revision; three potential solutions have presented themselves
(1) Use of ABS throughout the whole board will allow use of hook-tabs to more strongly connect everything, with the loss of the cool transparent panels
(2) Use of a wood will allow hand-sanded joints
(3) Small bushings on the legs
