A miniaturization of the Mendel design. The machine uses M6 threaded rods and M3 nuts and bolts (as opposed to the M8/M4 used on Mendel) and NEMA 14 steppers. The reprapped parts are about 30% of the volume of those for Mendel, which is to say it could reproduce three times faster.
Here's a close up rendered by M.BrittCrane:
I've found suppliers for all of the parts, and the estimated cost of the Mini-mendel would be under 350 euros (in Europe). Note that because the design is not yet stable, you may need to order more to get everything working satisfactory.

I've printed all RP parts in ABS, they weigh about 300 g. This means you can print 2 sets with your first kg of ABS if you use rafts. Blog posts related to this: -- Erik
ongoing development
- Main development seems to be going on in the RepRap-forum
- Marcus Wolschon is currently tryint to create a hollowed Mini-Mendel that used even less material. Prints and tests for mechanical stability will have to be conducted.
