This is a remote controlled stealth boat partly inspired by the stealth boat in the James Bond movie ‘Tomorrow Never Dies’, it is an open project which means anyone can remix and redistribute the design as long as credit is given (non-commercial use only). All the parts are 3D printed except for the electric motor, battery, controller and sealed bearings. Please note this is an ongoing project which will be improved and updated regularly.
I used the batteries, electric motor and controller from an existing rc car but you could source your own (the driveshaft existing cog file is designed specifically to fit the gear already existing on the motor I had). Bearings used were skateboard bearings (sealed) that are 22mm diameter, 7mm thick and inner diameter of 8mm. I used nuts, screws and bolts in the making of this boat (see our blog for how to insert nuts into your prints if you don’t know how or want to see how I did it).

Print level: Expert
Infill Level: %
Model originally printed on: Makerbot Replicator 2X
Recommended print settings:
Printed originally in ABS (tolerances may vary slightly for other materials), with 3 perimeters and 10-15% infill. The gears, driveshaft and propshafts were printed with 80-100% infill for extra strength. Supports may be required for some components depending on your print orientation.
Files of the bearings and electric motor used are included in the files so that you can source your own.
