6. Alternative Construction

6.1. Sliding. After making a number of models, I saw another possible way of constructing models of some of the regular helical star polyhedra. With a laser cutter I made paper modules of two connected equilateral triangles that could be slid together. This turned out to work fine for the UHSD 5-2(2) (regular helical star polyhedra based on the 5-2 star, shift 2 steps) (Figures 35-37) as well as for the UHSD 7-2(2) (Figure 38).

6.2. Stars 8-3 and 7-3. Even more complex members of the group can be made using this method. Figures 39-41 show the model of the regular helical star deltahedron 8-3(3) and Figures 42-43 show the 7-3(3).
