High Speed Tiny Trak

thingiverse

This is a micro fully 3D printed tank that has a first person view (fpv) camera on the front. Controlled by a remote control transmitter and a small brushed ESC. The tank is very quick and maneuverable and a blast to drive around the backyard. The 3D printed flexible TPU treads allow it to scale a variety of terrains and obstacles. Its small size allows for any space to become a new adventure! The parts listed below can be printed and assembled according to the photos above. If you have any questions please leave a comment! Happy tanking! Design Notes: Due to the heavy motors used in the design I recommend using some counterweight in the rear of the craft to help stop flipping. I used some nails to accomplish this but any small metal object will work. In future versions this will be solved so stay tuned for updates! Printing Notes: I printed the body and wheels in PLA using standard PLA settings. For the TPU treads, I used a flexible profile and printed very slowly with support on. I have also included a part called tread TEST PRINT where you can test your TPU settings without having to print an entire tread.

I have posted a link to a very small Frsky receiver that's more ideal for the size) https://www.banggood.com/2_4G-8CH-D8-Mini-FrSky-Compatibel-Receiver-With-PWM-PPM-SBUS-Output-p-1140478.html?rmmds=search&cur_warehouse=CN 1x 2s LiPo Battery (I use a 300Mah battery but the size can vary slightly. A 2s 500Mah battery is slightly too big for my tank but if it fits it'll work!) https://www.banggood.com/Giant-Power-7_4V-300mAh-35C-Battery-For-HCP100s-T-REX-150-F3P-p-987487.html?rmmds=search&cur_warehouse=CN 1x VTX (I use this small video transmitter but other very small VTXs work as well!) https://www.banggood.com/Eachine-VTX03-Super-Mini-5_8G-72CH-025mW50mw200mW-Switchable-FPV-Transmitter-p-1114206.html?rmmds=search Video:https://youtu.be/jxZkj3Deqsw
