- timonoko 2y agoThis works with two, but you need third to make 3D-reflector. There is no elegant solution except cutting 90 degrees slices. And it does not fold easily.
- ggm 2y agoslot 2 the way I described and then you only have to cut quarters for the 3rd disc. Making it demountable is about glueing tabs to hold things solid surely?
- timonoko 2y agoThe aim is to make it totally foldable and flat. For example: In life rafts they often have inflatable balloons, which have metallic foils inside in this 3D - configuration.
