vintage walking robot 3d printed Foki robot

thingiverse

You can 3D print this walking robot with lit eyes for very little money. It operates from a single AA battery. The robot was inspired by the 1960s robot game made in Argentina by DAISH, a company that created a game where robots' eyes would light up if you picked the right answer. This robot uses a low-voltage, low-current DC gear motor from SolerBotics, the GM7. It also uses the circuit board from a dollar store solar yard light to boost 1.5 volts up to LED voltage levels. When stripping down the solar light, keep the battery contacts as they will snap into the battery holder printed inside the upper body part. Print Settings: Printer: Flash Forge Dreamer Rafts: Yes Supports: Yes Resolution: Standard medium setting Infill: 15% Notes: The head was printed with supports and the crank leg linkage was printed with a raft. Other than that, you don't need supports or raft. I used PLA and normally print at about 210°C on a heated bed of 60°C. The ears are printed as flat discs, then I use a heat gun to warm them up and press them into the final shape. If I had printed the ears in the final shape, it would require a raft and supports, which would change the print time from 7 minutes per disc to about 20 minutes. You'd also have to try and remove the supports and raft without breaking the ear. Then there's clean-up time removing supports rough spots. Thermal forming the printed discs was so much faster and easier. Post-Printing How I Designed This: I used Design Spark Mechanical to do all the 3D part designs.
