This is a simple toy boat with some detail, but not very much. I am printing one for my 7 month old son, well actually it is for his room. Made in SolidWorks.
If you print this one without scaling, it would be about 10 inches long so you may want to scale it down before printing. I will upload a picture of the printed model when I have it done.
I made a 1/4 scale print on a uPrint. I left the bottom of the boat in the xy plane and printed with a layer thickness of 0.010 inches, with a low density infill. I have some banding on the deck of the boat, but the model printed in about 25 minutes with no problems.
