Lets Start A Riot upscaled

So at the request of someone, I upscaled the cannon to be 5 inches long.  Now I haven't ordered a test print of this and I don't really plan on ordering one.  THIS IS UNTESTED SO ORDER AT YOUR OWN RISK, the measurements should be correct but like I said I haven't ordered a test one.  I would have put this up for sale in Smooth plastic but it would cost like 133 dollars so yeah.  If you do have any issues with it please let me know so I can try to correct it.
