Universal PolyHedron Kit

Update 19/12/2023I have now added 2 extra rod ends which let rods come together at tighter angles.Update 23/11/2023I have now made all of the platonic solids using the parts,and uploaded pics.Update 25/10/23Overnight, I designed and printed some new parts, a "switch" for the Universal Polyhedron Kit. This set of 2 parts creates links between 2 parallel edge pieces, allowing joining of polyhedra sides. In the example pics, I have highlighted the 2 sets of triangles in blue and orange joiners. The ideas for this came from my work with basket cane, making twin edge polyhedra in spherical form. The draft writeup for the cane constructions is here http://modularbikes.com.au/docs/Twin-edged%20polyhedra%20and%20weavings%20from%20links%20and%20knots.pdf . I've included a diagram about switch placement in the pics. It should be fairly easy to make a model from a continuous set of rods, this needs 3 switches in the tetrahedron.Original blurbThis kit currently consists of 3 pieces, use 6mm dowel, and I have made a tetrahedron from them. The kit is male and female hinge halves, which are a bit like rod ends ( https://en.wikipedia.org/wiki/Rod_end_bearing ) . The hinges join rods together to form polygons. The polygons can then go on to make polyhedra with the help of the spacer part. All the other platonic solids can be made (in twin edged form) from the 3 parts and 6mm rod. The hinge halves add 15mm to each end of the dowel rod.For more pics, background and info, see http://tribo3d.blogspot.com/2023/10/universal-polyhedron-kit.html .Please post your makes, you will probably be ahead of me on making the cube, octahedron, dodedahedron and icosahedron etc.etc. etc.
