You've said it! I also use a CAD program (Autodesk Inventor) to model my stuff and I can imagine how hard it must have been to model this. It would surely take me more than a month to make this! And the program would be lagging really hard for such a complex shape...
доста работа е паднала. като гледам нивото на детайла, сигурно дори болтовете имат резба, а?
браво за търпението и упоритостта, личи си старанието определено.
It took me looking really close to see that this was CAD,
Very nice perspective as well!
Maybe the rear pulley's contact zone shouldn't be yellow ?
