A radio-controlled fishing boat that is suitable for exteriors, for example on a lake. The boat is almost 68 cm long, 20.5 cm wide and approximately 28 cm high. Parts of the boat are designed so that they can be printed on the MK3 printer. Since I plan to use the boat in the summer on the lake, I chose PETG filament for higher heat resistance. There are two options for installing the DC motor size 130 (Fig. 1) or 540 (Fig. 4).

The body of the boat consists of 5 parts that need to be glued together. Each part has holes for alignment pins. The following parts are required for the body of the ship.
