One more thing. Before I continue, I glued the parts that need to be reinforced onto stronger cardboard.
These go onto 0,5mm paper ...
... and these go onto 1mm paper!
The one with the two red "x" actually will be glued again as it needs to be 1,75mm
So for now I will put them under heavy books to press and wait until the glue dries! To be continued ...
