RC Dump Truck

Bring your mini construction site to life! This fully 3D-printed, remote-controlled dump truck comes with a trailer that can be hitched hands-free using a powered hitch. It pairs perfectly with the 3D-printed Skid Steer for building your own miniature construction fleet.

The dump truck isn’t just for show — it can haul small items like sticks, rocks, or even garbanzo beans, making playtime or demonstration builds extra fun.

Controlled using a PS4 controller via ESP32 and Bluepad32. Firmware can be customized for other controllers; full list of supported controllers is available in the Bluepad32 documentation.

Electronics, fasteners, and other non-3D-printed parts (including the controller) cost approximately $100. All parts except the tires are printed in PLA; tires are printed in flexible TPU.
