Print in place Circular Collapsible Bowl/Basket
I would first like to give a shout out to 3DPRINTINGWORLD whose work inspired this design. His basket design is https://www.thingiverse.com/thing:2901274
This Circular Collapsible Bowl/Basket uses the same collapsing technique as 3DPRINTINGWORLD's design, but incorporates a new handle system to collapse flat, hang as a basket, or support itself as a bowl.
The octagonal cross section of the handles allows for this versatility, while still being a simple design easily produced by desktop FDM printers.
As designed, the octagonal holes are 6mm wide, while the octagonal handles are 5.9mm wide. In my experiments, this 0.1mm offset provided a good fit between "peg" and hole. Not all materials or printers however are the same, so I have included a testing peg that can be printed quickly to test the fit before printing the handles.
Extra Perimeters Recommended
Two handles will be needed
Use Test Peg to test fit before printing handles
