Electra60 - 3D printed modular origami

Electra90 - Modular Origami Polyhedron Constructed from 90 Modules for Added Structural Complexity Inspired by the innovative designs of David Mitchell's "Paper Crystals" series, I sought to create a 3D printed modular origami skeletal polyhedron composed of 90 modules. My project draws inspiration from Mitchell's beautiful origami creation, "Electra 60," and can be viewed on his website or in his book. To achieve this, I have been working on an OpenSCAD script to generate the STLs with a manifold shape. Special thanks go to Laura Taalman (mathgrrl) for her valuable input and suggestions. Initially, the tabs were generated as separate surfaces, but we are still fine-tuning the code. The OpenSCAD script can be used to create single modules or a build plate with 15 modules, allowing users to assemble and print their models. It is also possible to view an assembled model, though it can be challenging to print. Customizing the gap parameters will help adjust the tightness of the joints according to the printed size. The radius parameter controls the finished model's dimensions, which point-to-point is just over three times this size - meaning the 80mm radius version I printed measures around 25cm across. I have also included STLs for single modules, build plates, and variant designs, such as spherical and those with baubles. A total of 90 single modules must be printed before assembling them using a schematic that indicates pentagons surrounded by squares with triangles filling the gaps between squares. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator Rafts: No Supports: No Resolution: 0.2mm Infill: 100% Notes: Please note that my printer and print settings have been adjusted for maximum accuracy. For your project, I recommend experimenting with different print settings to find the optimal results.
