About this 3D model

I go into detail on how to assemble the drive sprocket on my youtube channel: https://www.youtube.com/watch?v=oTmcSGYj9pk Extra materials required to finish: https://docs.google.com/spreadsheets/d/17GtRRScbmHi4SEwMbB6z7-BC1Aj2rZ2lGSjoywpuk9E/edit?usp=sharing The Maus parts need to be scaled up by 200% to become a ~1/16 scale model, because they were designed referencing a 1/35 scale model. This is one fileset of a larger project.
