3DRC RC Jet Boat Prototype

Last crawled date: 6 years, 1 month ago

A fully 3D printed RC jet boat. Requires a 9g servo, motor, ESC, receiver, and 2-3s lipo battery, along with some m3x12 bolts, some m3x6 set screws, some 3mm stainless steel shaft and a 3x10x4 sealed bearing.

Please respect the license and don't distribute without credit, or use for commercial purposes.

The main hull and mechanical parts can be printed in any material (I used PLA, and PETG for the impeller), but the seals and rubber washers must be printed in TPU or any other flexible filament. Only a few metres of TPU are needed, so a cheap 10M sample from somewhere such as rigid.ink will be enough if you don't have a whole spool of it.

I have designed this to be printable on low end 3D printers, and no parts need gluing together for assembly. All parts can be printed at 0.3mm, but I recommend 0.2mm for better quality.

Print all hull components at a low infill with 3 shells to cut down on weight, but maintain strength. No parts require supports if printed in the correct orientations.

I have added two different sizes of nozzles, 10mm and 14mm. I personally use the 14mm one, but I believe a higher top speed could theoretically be achieved with the 10mm one.
I recommend tapping all holes before bolting the parts together to reduce the chance of damaging them.
