concentric rotary switch (can someone make them ?)

So the rotary is fixed on the backside layer only? Would that help? The knob on the outer rotary will likely be large enough to cover the nut.Also, if the shafts of your rotaries are long enough, you could attach one more layer behind the panel, maybe 2mm alu sheet or so where you screw the rotaries on and fix that behind the whole thing..? Or make smaller pieces for each rotary..?//Tuomas

Nice solutions. I found another one myself: make screwthread in the aluminium square frame. So the upper rotarie is in fact attached to the frame without a nut. Then glue the frame to the panel. In that way it is still possible to remove the rotarie for replacement, service or whatever.
