It seems it's really hard to find a good, printable model of WALL-e so I was really happy to come across this one and was not disappointed. The different pieces also made it much easier to use multiple colours to have him look more like he should. I printed his head and hands using Filaments.ca silver PLA, his body with 3D Solutech real yellow PLA, and his tracks with Hatchbox black PLA. For finishing, once I sanded down the body to be nice and smooth, I masked off the areas that are grey in the different pictures I could find and then painted using Humbrol gray acrylic primer spray. I didn't do any weathering on him so this is more of a "showroom floor" version of WALL-e. Thanks so much for the model!
