Hi there! I’m sincerely hoping you will enjoy this 3D printed Jeep with tank tracks controlled by android phone! The construction is very simple, varying from one to two days to fully print & build it! To Control it you have to download in the Play Store the "Bluetooth RC Controller" app. Found stuff you will need in the instructions. Enjoy this project ! Cheers https://www.youtube.com/watch?v=imvT_zozXfk You will need few electronics things to make it: • 2 small Gearing Motor • 1 Battery LIPO 2S • 1 Arduino UNO • 1 Motor Shield • 1 Bleutooth Receiver • 4 LEDS & resistors for head light! • M3x30-35mm screw to fix the front wheel I printed tank tracks in NinjaFlex, but you could print in in an other flexible filament ! I give you links to stuff I have use to build mind! It’s up to you to use different but equivalent stuff.
