MakerBot Man Gears Up to Row His Boat! A PLA rowing boat, powered by MakerBot Man and a little help from the sun (or some batteries), is ready to hit the water. This amazing "thing" has several parts that work together in harmony: * The boat hull with a platform for the machine housing * The machine housing * Two crank shafts * Two oars and their supports * Two gearwheels, which can be printed or bought (depending on your preference) * A small geared DC motor * One or two small solar cells to harness energy from the sun * Some M3 stuff for assembly * And of course, MakerBot Man himself, printed at a scale of 1.5 All components can be printed with low infill and no support material is required. To fit on a 20x20 cm bed, print the hull 45 degrees rotated around the z-axis. The gearwheels used have a shaft distance of 28mm, 18/38 teeth module 1. If your wheels are different, simply adapt the shaft distance in the SCAD file. The place is indicated. Before gently pushing the motor into place, push the smaller gearwheel onto the motor shaft. Mount the larger gear wheel on a 35mm M3 shaft using two M3 nuts and a lock washer. Screw the crankshafts on at both sides and lock them with a nut/bolt combination. Make sure they are in the same position. When ready, mount the motor housing in the hull with four M3 bolts. After taking off his shoes, MakerBot Man is glued to his seat with a two-component epoxy adhesive. Snap the crank shafts into his hands and bond the seat to the hull at a position where the body follows the rotation of the crank shafts easily. If MakerBot Man doesn't pull the oars underwater but pushes them, swap the motor unit 180 degrees or reverse the wires of the power supply. The depth of the slot in the outriggers determines how high the oars are lifted. This might need some trimming depending on the weight of the boat. Just move the slot up or down in SCAD. Usually, rowing boats don't have a rudder. However, if you have a small pond, it would be nice to row in circles. That's why an invisible underwater rudder can be attached to the boat. Use the 3mm hole to attach your own rudder design. Buoyancy has not been tested... simply not enough Euros . Spray the hull with varnish to make it water tight.
