Clonedel is a modified fork of the Prusa Mendel, designed for easy casting by
Open3DP at University of Washington Solheim lab. Metrix Create
pace is making these parts -and- molds accessible at
Metrix Createpace If you are interested in holding workshops or just getting people building repraps, you can pour and demold a full set of parts in a little under an hour vs the normal printing process.
Holes are not pre-drilled, so you can build metric or SAE, depending on what is cheap in your locale.
The X motor bracket and idler are probably the most noticeable changes at the moment, with more changes coming in the coming months.
Currently parts are being cast in 2 part urethane (1:1 by volume or weight) from smooth-on. You can experiment with materials quite easy if you have molds, and there are thousands of urethanes to choose from with different hardnesses and psi. We have found that the casting material we are using is very strong, not brittle, and retains some flexibility, much like RP parts. It also doesn't smell bad. It is easy to mix in color as well as filler for fun or added strength.
I am generally on #reprap if you have questions. I will be posting more documentation on the whole process as I get time.
