- notch back to 0.4 mm (from 0.3mm)
- make lower part of outer wall thinner by 0.1mm (0.5 mm -> 0.4mm)
- move inner wall in by 0.1 mm
- move outer wall out by 0.2 mm

version 1: InnerClampWidth = 2.2 mm  -> needs lots of force to mount&unmount
version 2: InnerClampWidth = 2.3 mm  -> t.b.d.

- ahorn suggested that a chamber would let tall people better see the display
- reduce total thickness a bit (no need to completely cover the screws
  but keep it thick enough to guide the finger along the touch surface)
- optimize cutouts for electronic parts to keep enough distance to top
  layers
- try to make foil in front of the display even thinner

I'm not sure whether there are any real changes or only autosave...
