The proko-rc05 is a radio-controlled car built to carry an entire custom 3D printer while driving and jumping. To cope with the printer's weight and high center of gravity, the vehicle uses a wide 2WD buggy layout and weighs about 3.7 kg in total.

The printer itself was newly designed for the vehicle around a Core-XY mechanism with a 53×53×50 mm build volume. A 90-degree hotend modification was intended to keep the machine low, but filament leakage prevented printing, so the event demonstration ran without extrusion. It was created by proko.
