02-14-2016: Kirby Downey published one of the most astonishing and demanding free 3D printing models ever designed on MyMiniFactory
Detailed AT-AT from Star Wars Scale 1:75
On February 14, 2016, Kirby Downey—who at the time was the lead designer at MyMiniFactory—released an iconic 3D printable model: "Detailed AT-AT from Star Wars Scale 1:75." It had 15 points of articulation and showcased the interior of the machine. The model consisted of nearly 70 parts and could be assembled without glue. 3D printing time? Officially 65 hours, though some users reported exceeding 100 hours…
Once printed and assembled, the model stood 30 cm tall and weighed nearly 600 grams. Downey optimized all files for ideal print orientation with minimal support requirements. The default layer height for the model in the photos was 0.2 mm. The first version was printed on a MakerBot Replicator 2 using Formfutura Light Grey PLA.
But don’t be fooled by this description… While truly spectacular, in 2016, the AT-AT model was extremely challenging to produce and required a completely different mindset than the usual "I'll print this because it looks cool." Some parts were very demanding for that time, and relatively few 3D printers could handle them properly. I personally used selected components for quality testing of 3D printers, which I later reviewed in my articles on Centrum Druku 3D.
By the way, I still have the full set of files archived on my computer, but I never actually committed to printing the entire model. Although today, with the current generation of desktop 3D printers, it shouldn’t be as much of a challenge as it was nine years ago. The real challenge now would be the dedication to the project and the patience required for production and assembly.

A few final words about the author of the model—Kirby Downey. At that time, he was a renowned 3D prop designer, specializing in video game weapon replicas and cosplay props, working for MyMiniFactory. Originally from South Africa, he studied Industrial Design at Tshwane University of Technology before moving to London. His passion for gaming led him to 3D modeling, and his designs quickly gained global recognition.
Downey became internationally famous for his complex projects, from mechanical models to massive weapons like Frostmourne from World of Warcraft. He shared his work through YouTube, MyMiniFactory TV, and live streams. He was also a panelist at London Film and Comic Con, where he showcased his expertise in 3D-printed props. Since 2017, he has been working as a senior production technician at 3DPRINTUK.
