Another Balloon Boat

I designed and printed a balloon powered boat for my son's birthday last month. Blow up a balloon and stretch the the balloon opening over the hole at the top. I did find that once the balloon is attached, it's easier to inflate by blowing into the bottom of the boat rather than taking the balloon off each time.

There are 2 prints, the boat and a name plate. I'm not sure how to make the name plate customizable in thingiverse so I included a blank that you can download to edit the .stl, or, probably easier, just make one in the software of your choice - it's a 70 x 22 x 5 mm slab with a name cutout. The boat works just fine without the nameplate.
