A Nazi German Tank from world war two. Only two ever built. The biggest tank ever built! Sorry if images are bad :(
Just always make sure if your 3d printer has a heated bed to level it after it gets to the right temperature.
Overview and Background
to be safe
After you tank the tank model off the raft be careful when taking the supports off.
Lesson Plan and Activity
Shouldn't take more than 10 minutes to get your printer going from including leveling and heating. If you print it the size that I did it should take around 2 hours. Less if you have upgraded the print speed on your printer.
Printer, filament, some time, and some patience.
