YouTuber ProfessorBoots has cooked up one thing particular: a 3D-printed remote-controlled dump truck that’s as a lot a desk toy as it’s a jaw-dropping dialog starter. Don’t count on to see this beast on a building website, nevertheless it’s bought sufficient smarts to steal the present wherever.
The truck is cut up into two sections—a six-wheeled tractor and a side-dumping trailer. The tractor, constructed to really feel like a mini semi, rolls on six wheels. The good function? A magnetic hitch that pops out and in with a flick of the distant, connecting to the trailer with energy and management strains that preserve all the things in sync. It’s not simply towing—it’s a slick, shifting system that feels alive. The trailer’s no slouch both, tilting its load left or proper like a professional, able to dump no matter you toss in it.

ProfessorBoots leaned onerous into 3D printing to make this occur, turning a hobbyist’s dream into actuality. The tractor and trailer are principally printed from PETG filament, robust sufficient to take a beating whereas nonetheless straightforward to work with. For the suspension, he switched to TPU filament, whereas off-the-shelf wheels have been for higher grip relatively than printing them.
An ESP32 microcontroller runs the present, taking orders from a customized RC controller. This isn’t your primary point-and-go rig—it’s a finely tuned setup that handles the tractor’s drive, the hitch’s dance, and the trailer’s dumping with pinpoint accuracy. A brushed DC motor, powered by a 3S lithium-polymer battery, offers the tractor the oomph to haul its load throughout a desk or via a yard. The hitch even passes energy and alerts to the trailer, making that side-dumping motion silky clean.
