: The Lemontron is a unique open-source 3D printer that you can assemble yourself. Designed for portability, it fits into a filament box and costs about $413. Though it requires an existing 3D printer to create some parts, the Lemontron's upside-down design does not alter the printing process. Its compact size offers convenience for travel, even though it won't replace standard printers.

The Lemontron is an open-source 3D printer designed for those who need a portable solution. It can be assembled using parts that fit into an empty filament box and costs approximately $413 for components and a custom PCB, though it requires an existing printer to print certain parts.

Despite its compact size, assembling the Lemontron is not a beginner-friendly weekend project. However, a YouTube DIY guide by Lemontron simplifies the process, offering clear instructions on sourcing parts, setting up electronics, and assembling the printer effectively.

One unique feature of the Lemontron is its upside-down printing orientation. This design choice doesn't affect the printing process but offers better portability, with heavier components at the bottom, maintaining familiar 3D printing workflows while enabling easy transport.
