Tiny Robot

thingiverse

I was inspired by projects like the Maker Faire Robot, the Ultimaker Mascot, and others. I wanted to create a simple robot print for a FIRST Robotics team table handout (Team Inconceivable!). After several iterations with larger arms, smaller arms, rotated arms as ear antennas instead of arms, numbers on top, flat on top, experimenting with overhangs, bridging, and more, I settled on this design to share. It balances well and can be used for robot stacking games. Print time is a little under 20 minutes on any of my printers. The best combination of weight, strength, and speed that I've found is two shells, .2mm layers, 20-30% infill, and two top and bottom layers. At 25% infill, it ends up being right around 1m of filament. For numbers or letters, I put them in the top and recessed them .6mm. Adding lettering means your first layer adhesion has to be pretty good for clean letters, but it's quick and easy to add in Tinkercad or any other program.
