I seem to be having a problem… I have always had this problem. Plastic molding. Saaaay… I’m building a robot, with all of those gears, pulleys, you know, mechanical stuff. How do I mount them? Mounting, and plastic molding I have always feared. You know, like, when you take apart really anything with wheels that runs on a motor, you see TONS of little tiny raised holes, and… just a bunch of little plastic “holders” that gears are sitting in. (Then, when your done fixing/looking at your little box of gears, you can’t put it back together because one little gear is slightly off, or upside-down or SOMEthing.) So, if I need to make something like that, how can I do it? Please help! Thank you.
