Retro Robot

The Retro Robot is a fun model perfect for any office or home. It's sure to impress people whether it's inviting them into your workspace or wreaking havoc on a LEGO city. This ball-jointed robot can be posed in almost any way and still assemble easily from its separately printed parts. The models shown above were printed at 75% scale (except for the tiny one, which was printed at 25%) using my CraftBot+. The model on the right of the second image is an early prototype that had larger ball joints. Unfortunately, these large joints caused it to break in several places during assembly, and I changed the design to use smaller joints instead. The other model, on the left of the second picture, was the first redesign and came together smoothly. Print Settings: Printer: Craftbot+ Rafts: Yes Supports: Yes Resolution: 0.200mm Infill: 19% Notes: Make sure to print all parts with their backs facing up. Also, pay close attention to supporting the parts as needed, especially around the pegs on the male ends of the ball joints. I printed the models shown above at a 75% scale and found that I needed a resolution of at least 0.200 mm to get the eye sockets right. I also increased the layers to 5 because several of my first prototypes had holes in the exterior. Printing it at 25% scale worked, but it's very fragile. Post-Printing: To assemble the pieces after printing, line them up as shown in the photos below. Adding googly eyes can add an extra bit of fun.
