Motorized Star Wars AT-AT

thingiverse

This is an operational model of an AT-AT from the Star Wars films. Powered by a 9V battery and 90 rpm motor, its mechanics rely heavily on precision engineering. Roughly 750 grams of filament was used to print nearly every component through three-dimensional printing technology. Watch this short video of it walking here: https://www.youtube.com/shorts/Igenerated Morbihas performed a remarkable makeover on the design, allowing parts to work better and print with less stress, and I recommend you check that out at thingiverse.com/thing:2043900. Additionally, credit goes to DoBrinK for refining my original model, resulting in cleaner prints, and providing high-quality videos. His improvements truly elevated the entire AT-AT design experience! Breaking down this design is an ambitious undertaking involving a staggering 69 individual parts (28 STL files). However, printing these pieces on your 3D printer is a more manageable process due to their small size. With an efficient setup, I was able to print every part within four days. But make sure your 3D printer meets certain specifications before embarking on this project, particularly in terms of space requirements - we are talking about a large model measuring nearly a foot tall. Allowing for smooth surfaces, your machine will have an easy time with all parts; the smallest one, measuring around half an inch long. All you need to supplement these printed parts is a 90 rpm motor rated at $13 each, a $0.759V switch for control, and another $1.25 9V battery clip to house the energy source powering your AT-AT model (you may find existing clips from around the house that'll fit this part). Use the glue stick mentioned earlier to make the entire assembly look polished. Reach out whenever doubts occur.
