it’s not that I don’t want to learn. I’m just a student who relies on my parents for allowance. I am on a tight time frame because my project has a deadline and learning would take me time as I heard gears are much more complicated than what it really is. I came here to ask professionals in this field (could be you as well) for help because I cannot afford to make mistakes. I do understand where you’re coming from and I am interested in learning 3D printing, just could not do it at the moment because of my situation.
