Community, I have a discussion. Take a look at the linked model then join the discussion. I am trying to wrap my head around this. First, you'd have to assume there is no slack between gears (I am aware there is plenty). If there were no slack, wouldn't there be an ever so slight movement at the last gear even if it were in the subatomic range. I realize the ratio is reduced but movement drives movement at a smaller ratio, so there should be SOME movement even if impossible to see... Right? I'd love to learn.

How can I rate a model 5 stars if the system doesn't realize I printed it. I downloaded a model, made some modifications so I saved it as a new project. I then printed the project and want to give a rating to the designer but it says to give it 4-5 stars I would have to have a completed print. I do, it was just renamed so it isn't recognizing it. This is the model https://makerworld.com/en/models/653444-my-desk-organizer#profileId-618217. Pic shows it printed.
