I have no previous experience with 3d modeling or 3d printing at all. This is my first project and I would like to have some input as I know for sure this isn't as good as it can be. I tried to make the walls as thick as I could without making the prop too "fat" but I have my doubts on certain parts on it. It's inspired by the hidden blade from assassins creed and I tried making it as functional as possible, without the lethality of course. The thing I am most worried about is the wheel locking mechanism, I whipped up something quickly as I couldnt figure out a clever way to do it at the point of writing this. Can you spot any glaring mechanical errors? Some parts will have either springs or rubberbands between them so what you see if not all there is to it. Would appreciate some feedback, also ideas on how to improve the design are welcome.
