* Check Maytec profiles (40-50); center holes for screws
  * Check plastic caps for the Maytec profile counterbored holes in the plastic
  * 2 mm extra on both sides of the glass channels. depth? ask vacuum workshop
  * radius pocket insulation of the plastic
  * o-ring size?
  * in general corners: sharp 90 or round?
  * Holes in plastic to maytec in the corners are wrong
  * plastic plate bigger, so the maytec profiles don't make uncomfortable to work with the led cooling/system
  * study the possibility of making outer glass bigger, to easy the led cooling/system. it doesn't fit
  * check proper dimension of led pcb. Connector. ratio cables/leds. dimensions as they are
  * copper pipe above or below the plastic plate?
  * collector with round shape? yes, except where the archimedes is
  * 
  * 
  * screws from brass plate to alu plate
  * collectdor isopropanol, next to alu plate
  * luzius, archimedes, stainless steel, bending, dimensioning
  * check if we can cut out a corner of brass plate for space for archimedes
  * leave the cooling pipe above the plastic plate and cover it
