The parts were all printed on my Sunhokey Prusa i3 clone (significantly modified), using various brands of PLA, and after a few minor jams, everything came together. I started out printing early parts with whatever filament happened to be in the printer, and, then decided that it looked like a patchwork project, so, I started using as many different colours as I had on hand. Hopefully this helps you see the different parts more clearly in the photos. Tools used: Computer: Macbook Pro Sketching: Paper by 53 on an iPad Modelling: Rhino 3D, Lightwave 3D and MeshMixer Printer Controller: OctoPrint running on a Raspberry Pi 2 Slicer: Simplify 3D Bed Surface: PRINTinZ Filament Used: Purple parts – MeltInk PLA Orange parts - HobbyKing PLA White parts – CoLiDo PLA Black parts – AMZ3D PLA Light Blue – Solutech PLA Yellow parts – eSun PLA Red parts – HobbyKing PLA Gold parts – MG Chemicals PLA Printer Settings: Nozzle temperature: 230 degreesC (it is colder in my basement shop) Bed temperature: 50 degreesC Print Speed: generally around 40 to 50 mm/s Infill: 15% to 50% depending on the part Layer Height: 0.2mm Supports: only as needed Fuel: Diet Pepsi YouTube breaks - thanks to various 3D printing related channels that kept me going some late nights During this project, I really appreciated some of the tweaking features of Simplify3D, and the ability to restart a print came in handy on one of the larger bevel gears. It also gave me a chance to try out my new PRINTinZ print surface which made most prints pop off easily. Sorry that the assembly view isn’t done right. There are just too many parts (over 55 plastic parts) to get them all aligned properly. If you actually try to build this, and need help, please feel free to contact me and I will help.
