This is a pirate ship (kind of) that I made for my 5 year old. Has a hidden cargo hold and crows nest for some little figures. I have not tried it, but i think its probably top heavy, if you want to float it you will probably have to add some weight to the bottom. Pretty easy print, put the ship right side up, multiply the mast and print two, flat side down. Print ten cannons and glue it together. Cover for the cargo hold just sets on top. Print two railings flat side down and glue onto deck. The railings may be just a bit too long. Last is the steering wheel (ikd what it is in pirate terms). Also you will notice some little clip things on the mast, for attaching a sail. Happy sailing, yo ho ho!
