Mirandetta: the 3D printed electric motorcycle disassembles to fit in a suitcase. And you can print it yourself too
Ivan Miranda has made available the design files for the Mirandetta, his 3D printed electric motorcycle that can completely disassemble to fit into a suitcase. The maker and YouTuber sells the files for $40 on his website, targeting those who want to build the vehicle they admired at the Maker Faire in Prague, rather than just looking at it.
The first prototype was created in about ten days as a sort of travel hack: the smallest motorcycle an adult could ride that could still fit in checked luggage. To achieve this, Miranda used aluminum wheel axles and an entirely metal steering column.
In the newly released version, those two components are now printed pieces, and every part of the motorcycle has been redesigned to fit on a 300 x 300 mm print bed. Miranda has also standardized the lighting system using commercial T10 automotive sockets and bulbs, instead of the salvaged pieces from the first version, and has reduced the number of different screws needed for assembly. He admits that the redesign was more labor-intensive than building the original prototype.
Lawnmower wheels, floating brakes, and screwdriver batteries for power
The wheels are fitted with lawnmower tires, which are typically too flat to lean into corners. Miranda has printed narrower rims than the standard, so the inner rings of the tire bead stay closer together: once inflated, the sidewall cannot spread apart, and the tread assumes a usable profile when leaned over.
Braking is handled by floating motorcycle discs instead of bicycle ones, as the former can be modified to accommodate a larger central hole, allowing the printed axle to pass through without risk of shearing. The rear transmission is belt-driven, while the throttle is a 10K linear potentiometer managed by an Arduino connected to the motor's electronic controller.
Power comes from two interchangeable 36V battery packs for electric tools, which are easier to carry through airport security than a dedicated lithium pack. A DC-DC converter lowers the voltage to 12V for the horn and lights. Without the batteries installed, the motorcycle weighs a little over 14 kg.
The specified printer for this project is the Prusa CORE One L, with a print volume of 300 x 300 x 330 mm: the standard CORE One model, limited to 250 mm, cannot accommodate the larger components in one piece. On Miranda’s website, the files include the original Fusion 360 design, exports in STL and 3MF, and a partial list of components to source.
Miranda is explicit in the warning posted on the product page: the Mirandetta is intended for educational purposes and the result should not be used as a real road transport vehicle. He also reiterates that he does not provide any support: he will not answer questions or assist anyone encountering problems replicating it, leaving the community of a dedicated Discord channel as the only point of comparison among makers.
The creator himself, speaking of the vehicle, has humorously described it as "super fast, definitely too fast" for its size. It should also be clarified a common misconception: the assembled motorcycle does not fold for transport; it is the disassembly into individual parts that allows it to fit in a suitcase.
With this hobbyist prototype, Miranda still won the suitcase construction contest at the Maker Faire in Prague and plans to bring it back to Open Sauce. He describes it as a complicated hobbyist build, not a project intended for mass production.
