THIS PRODUCT ONLY INCLUDES DIGITAL FILES FOR 3D PRINTING
This is a improved version from scratch of my previous 3d printed rc boat. It has been designed for speed and is a lot faster than my last 3d printed rc boat despite that I used the exact same electronics and hardware. The main inspiration is the Pursuit from TFL hobby. My top speed record is 83,2kmh using the setup down below. Biggest hull section part is 205mm high and 240mm wide, which makes the boat ideal to be printed on a Prusa MK3S+/MK4 or anything similar in size. I have designed it to fit a TFL carbon motor mount at the rear, and a rc boat metal hardware kit from ebay at the transom. An optional transom without pre-printed holes is included for those who wish to put their own parts.
I have printed my boat in white PLA, super glued the hull sections together, and then fiberglass reinforced it using 110g/m^2 glass weave and laminating epoxy. I did this because the hull thickness is decreased to 50% of my previous boat. Now it is 1.75mm thick. I wanted a lighter boat for more speed. Then I spray painted it and applied clear laquer.
A nice feature with this boat is that you can modify and remove the bolt-on transom if your specific parts does not fit. This also makes it easier to fix your boat if for example something hits the rudder at high speeds and the rudder mount breaks.
