About this 3D model

Overview: This model has only three differing parts: A right and left arm/segment (1&2) and a four-point joint connector. Each arm has an extruded profile on each side which was made to allow the maker to differentiate between arms/segments. These will only connect to each other on the flat back side of each arm/segment. This model also takes advantage of the use of your scrap filament for its hinges/connection method. All connections are also press fit into place and require no glue for assembly. Alternatively, you can also use a *soldering iron to further secure each connection but this is not entirely necessary for my model. I'm aware there are existing Hoberman Spheres available on various websites but I aimed to make one similar to Siberk's Cuboctahedron style version on Thingiverse. This kit has quite an assembly process so be ready to work with small parts, pliers, a flush cutter, screwdriver or small metal rod (used to press filament into place), filament bits and a hard surface. Total time for assembly was about 3 hours but expect a longer time if you struggle with small part assemblies. What You Need for this Project: Tools Pliers Flush Cutters Calipers for Filament Scraps (you can test fit and eyeball as well) Screwdriver or similar (something with a small metal tip) A hard surface (*Optional) Soldering Iron Printed Kit Cards 1x - Main Ring 1 1x - Main Ring 2 2x - Mid Section 1 2x - Mid Section 2 2x - Triangle 1 2x - Triangle 2 Printing all these cards with yield 48 of each arm/segment for a total of 96 arm/segments and 24 4-Point Connectors. See the attached PDF for assembly. I hope you enjoy this new iteration of the Hoberman Sphere!
