Cutting the frame correctly meant that the design worked.
The stairs worked however the frame was too fragile and snapped- I could improve this by reducing the size of the stairs so that the frame can be thicker and more resistant to snapping.
The bowl did not work as the circles in the middle were too small and the structure of the material meant that there was wide gaps between the corrugation and not enough friction to hold the joints in place- I think this would work better in a different material.
The three plane design worked and held together.
The Four plane was successful and created a snug joint which formed a very sturdy square however the detail in the middle is very fine and fragile and the nature of the corrugated sheets meant that the layers began to flake or pull away from each other where it has been cut.
This an adaption of the additive print- However the rings were too small again and the scaffolding was to tough to remove from the exterior of the design
