Hey, I noticed a little thing that is really minor, but might deserve being looked into. I believe that part 4716 (worm gear) is too long in Mecabricks. In MB, the part is exactly 16 units long (2 bricks). However, I think it is actually less than that. (4 and ⅚ plates, or about 15.26667 MB units. I could be wrong, and I know this is a really minor issue that we could fix by overlapping parts slightly, but I thought you might want to know.
