RCP Non-Proportional Octahedron

thingiverse

This is an octahedron puzzle, similar to a Rubik's Cube. Here's a quick video of it working: https://www.youtube.com/watch?v=r3ucQBgF01k&feature=youtu.be You'll need a core with screws and springs to assemble this puzzle. It has been designed to work seamlessly with a Guanlong core/springs, which can be purchased for approximately $4. Print Settings: Printer Brand: LulzBot Printer: Mini Rafts: No Supports: No Resolution: 0.2 Infill: 20% Notes: Only the center pieces require supports; all others will print perfectly without. Post-Printing: After printing, I recommend sanding the pieces smooth for optimal operation. I use 180, 320, 600, 1000, 1500, and 2000 grit sandpaper to achieve a polished finish. The cube in the pictures has only undergone the initial steps of sanding and still needs further polishing. How I Designed This: This puzzle was designed using Blender. Recently, I created a series on building similar puzzles; you can find that series here: https://www.youtube.com/playlist?list=PLZkuAJ0-o0VbbvaFc7B0BP71LlzoRrWl0
