LDO Motion's MOG RC Truck Kit Packs 582 3D-Printed Parts Into One Build

A Kit That Eats Filament and Spits Out a Truck

If your 3D printer has been collecting dust printing benchies and phone stands, LDO Motion has a more ambitious weekend project for you. The MOG RC Truck Kit is a fully 3D-printed tribute to the Unimog U5023, and it arrives as a box of 582 parts spread across 101 print plates. That is not a typo. This is a build that demands patience, calibration, and probably a few extra spools of filament.

LDO Motion, best known in the maker world for stepper motors, motion systems, and Voron printer parts, is now selling the kit through its own store. The company says the design is optimized for desktop FDM printers and only needs a 180 x 180 mm build plate to get started. So even a modestly sized printer can tackle it, though you will want a machine you trust to run overnight, several nights in a row.

What You Actually Get

The MOG is not a toy shaped like a truck. LDO Motion claims the finished model has functional portal axles, a realistic drivetrain, and scale details that match the real Unimog closely enough to please RC enthusiasts. The portal axles are the standout engineering detail here: they raise the axle center above the wheel hub, giving the model extra ground clearance without raising the chassis. That is the same trick Mercedes-Benz uses on the real Unimog to clear rocks, ruts, and uneven ground.

All 582 parts are pre-oriented in the included plates, which should save builders from the usual guesswork of figuring out which side of a part should face the bed. The kit also links to a Google Slides build guide and a community of build streams on YouTube, including series from Canuck Creator, DWIT, DigitalDrangon72, and ModbotArmy.

Who Is This For?

This is not a first-weekend project. It is a commitment. If you have already built a Voron or two, upgraded your hotend, and printed your own replacement parts, the MOG kit probably feels like the next logical step. If you are still wrestling with bed adhesion on a stock Ender 3, this build will test every weak point in your setup.

The price and full BOM are not listed in LDO's preview, but the model file is hosted on Cults3D, which suggests the design is either free or sold as a paid STL bundle. Buyers will still need electronics, tires, hardware, and a radio system to bring the truck to life.

The Bottom Line

LDO Motion's MOG kit sits at an interesting crossroads. It is part model kit, part RC project, and part endurance test for your printer. For makers who want a single build that justifies months of printing, it is one of the most substantial desktop 3D printing projects we have seen this year. Just clear your schedule, stock up on filament, and maybe print a few spare parts before you need them.
