3D Printed speed boat

Michael Christou shares on Thingiverse:

Speed Boat 3 RC

I broaden the front part of the hull so there it could may be possible to drive it also with an air propeller.
To day I tested the air propeller but I had only a 2 cells lipo and that wasn’t enough to make really speed.
The powerful inboard outrunner was driven with 4 cells lipo and made the boat by far much faster.

Update 07.31.2015
To day I tested the air propeller with another motor (STORM 1806 2300kv) and with a 4 cells lipo. Its much faster now:

But it isn’t optimized yet. Full throttle pushes the bow down and breaks the speed.
Attention
Use the propeller mount with the protection ring only in still air, otherwise it will capsize for sure!
That’s why I designed the slim version “propeller mount slim”.

The hull consists of 4 parts, the longest is 180mm. Therefore I uploaded the complete hull, so you can slice it in smaller pieces. This is very easy to do with netfabb or another program. If you have difficulties, I can do it for you, but the smallest possible part is 130mm.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
