I printed this cool little paddle boat over the weekend. It was simple to print and just needs an elastic band to power it.
The model was made by user swtchrwr on Thingiverse.
Click here for a link to the model and the settings I used to print it. I printed the hull at 5% infill to make it nice and light.
Because the boat at full scale was too big for my printer I printed it at 60%. The pegs and paddle were too big for the hull so I printed the paddle at 50% and the pegs at 60% with a few mm taken off the width and depth.
Hopefully I will be looking at printing a steam powered boat next.
