Little bathtub tug boat + hex nut weights

thingiverse

Based on the awesome tugboat by vandragon_de, I wanted to save on filament and gain more control over weight distribution to ensure the boat stays afloat in the choppy waters of the Bathtubbian Sea. So I designed this version, which can hold up to three M10 hex nuts inside its hull, keeping most of the weight submerged underwater. To print this, you'll need to insert a command for pause or filament change via slicing software or trigger it manually while printing. The height for that should be precisely 10.40mm. There are two versions because I learned that there are different types of hex nuts: M10 [ISO] hex nuts have a spanner size of 16mm. M10 [DIN] hex nuts have a spanner size of 17mm. Please make sure to use the correct file based on what you have. I recommend no more than 10% infill for the rest of the model, or it will become too heavy and prone to capsizing. By the way, I also filled the gap under the barrel because it caused unnecessary bridging issues.
