One recommendation I require is, for the PCB and plate cutouts, how much allowance should I have? At the moment I have 1.5-2mm, I think this is too much, and feel that for the plate I should have it .2mm smaller than the plate dimensions, as laser cut acrylic seem to have a very high tolerance, because the acrylic is literally melted at the laser points. For the PCB layer I will leave it as it is.
