Steam Boat

thingiverse

On a Sunday afternoon, I craved for a quick DIY project and stumbled upon plans for a putt-putt boat. Initially, I used a milk carton to shape the boat but realized it was no longer waterproof. Thus, an old protein bottle's boat-shaped cut came to my rescue. Eventually, I designed my dream putt-putt boat. The boat can be printed with or without support material, but if you choose the former, only external support is required since removing internal ones could be a hassle. In my case, I opted for no-support printing, which needed minor cleanup inside and on the bow. I printed it using two shells and 10% infill. The engine's instructions can be found at http://www.sciencetoymaker.org/boat/. Once assembled, attach it to the boat with a twist tie. To prevent water leakage, cover the straw hole and twist tie holes with two-part epoxy. Secure the tea light using a loop of tape or double-sided tape.
