few days ago when i was cutting acryallic sheet for my project it was kind of really tuff so insted of hand cutting i decided to make a laser cutting machine so at first i find right parts to build then i design 3d models for mount all motors bearings and other parts after that i created the repo and add all minecar parts to build it and i understand that it is quite complex to understand so i would make a tutorial video while building it:)
