3D-Printed Electric Motorbike That Folds Into a Suitcase Goes Open to Makers

Engineered Around a Single Print Bed

A central constraint of the project is that every component must print within a 300mm x 300mm build volume. The reference machine cited is the Prusa CORE One L, which offers a 300mm x 300mm x 330mm build area, a printer Tom's Hardware has reviewed previously. Smaller machines, including the standard 250mm-class CORE One, cannot accommodate the largest parts in a single piece.

The wheels present a particular engineering challenge. Miranda uses lawnmower tires, which typically have a flat profile that is not suited to leaning into turns. To work around this, he printed the rims narrower than standard so the tire's internal bead rings sit closer together. Once inflated, the sidewalls are prevented from splaying outward, which rounds the tread and makes the tire more suitable for a leaning two-wheeler.

Why It Matters for Makers

The release lowers the barrier for hobbyists who want to fabricate a compact personal electric vehicle at home, provided they own a compatible large-format printer. By standardizing hardware around common automotive parts and constraining geometry to one print bed, the design aims to make replication more practical than a bespoke prototype.

Tom's Hardware reported that Miranda has warned the vehicle is very fast, cautioning that it may be too fast. That framing underscores that the Mirandetta is a functional, high-performance build rather than a novelty, and prospective builders should weigh safety and local regulations governing personal electric vehicles before riding one. The project reflects a broader trend of consumer-grade 3D printers enabling increasingly ambitious mechanical builds outside traditional manufacturing.
