Mechanical Reduction System Assembly

(Old student project) Full working assembly project of a speed/power mechanical reduction system with mechanical gear mates. Multiple Full HD renders. Operational for motion study, just add a rotary motor on the first shaft. It might take a more powerful PC for a good frame rate considering all the parts. This is for educational purposes only. Any questions and/or pointers are welcome. P.s. Bearings are simplified because i couldn't find the ones I've calculated in the toolbox.
