Grain Bin

Hi I am new to 3d modeling so any feedback is appreciated. This is a Meridian 1/64 scale hopper bottom grain bin (roughly 4000bu) that I built in Tinkercad. Designed to print upside down in a single piece. I made it for my nephew so it has very thick walls to stand up to play time. If you have good adhesion it should print with a raft and no supports, otherwise print with table supports only so that the entire bin isn't filled with supports. Printing time is roughly 15hrs. Enjoy
