Kids Bottle Boat (Raft)

thingiverse

This is a support for a raft you can make from two plastic water bottles. It was designed specifically to fit the Costco Kirkland Signature water bottles and features a short mast for a straw. A sail can be easily taped to the straw and also securely fastened to the mast at the bottom to prevent it from spinning out of control. For some unknown reason, the mast part warped when I printed it, but hopefully that was just an isolated anomaly in my print.
