The Bonsai RepStrap is a development by Peter "Sci" Turpin. It aims to be a small, lightweight 3D printer that can be used for making the parts for larger full repraps.
A recent attempt to make the basic structure easier to ship without having to outright dismantle it may mean the Bonsai can be repeatedly folded up easily. While not the original goal of the project, this may have the added bonus of making the first readily portable 3D printer.
Collapsible frame
Starting with a Mendel style frame, as it would be a low-mechanical-stress design, half of the A-frame is removed and the Z-axis doubles as the upright support. Here is a brief video clip of prototype folding mechanism:

Notes
Simplified Mendel-type frame design Geared low-power motors Wire belts Studding sheathed in tubing to dual-purpose as runners for print bed Bordon-cable filament feed Have enough surplus stepper motors to make approximately 500 machines, if the design works out. Aiming to make and sell for aprox £150-200.
Background
2000 surplus stepper motors must be useful for something.
