What is the Clonedel?

<flickr>5505230025|right|m</flickr> The Clonedel is a RepStrap design which is essentially a Prusa Mendel that is modified for easy casting.

The design goal of the clonedel is to make production of plastic parts trivial. Using a set of molds and 15 minute cure urethane, you can have a full set of parts in under an hour.

Parts are being redesigned to make them use less material, and easier to demold. They are also being redesigned to take into account the properties of the materials.

You can currently get molds and parts at Metrix Create:Space Clonefactory page, or make your own by downloading the files from the Open3DP github.

For maximum resolution of master plates, it is recommended that you use a powder-based printer.

Where did these parts come from?

If you got your parts from Metrix Create:Space, they were cast out of a two-part urethane cold-casting plastic compound, called Smooth-On Smooth Cast 325.

The original (positive) masters of these parts were printed on a Zcorp Z400 powder printer at Metrix Create:Space in Seattle around the beginning of March 2011. The design is from Mark Ganter’s lab at the University of Washington, and is a modification of the Prusa Mendel for easy casting.

These parts were printed from the designs located on our GitHub page.

How do I turn this into a Prusa?

Tools and Supplies

  1. One set of parts
  2. Drill bits:
    1. 3mm
    2. 4mm
    3. 8mm
  3. Tap
  4. Knife (a box knife will probably work)


  1. Remove the parts from the shipping container.
  2. Use the knife to clean the flashing off the parts.
  3. Locate a drill press and drill out most of the holes with the appropriate size bit. The parts have divets to help align your holes.
  4. Tap the setscrew hole on the small pulleys with the tap.
  5. Follow the instructions for the [Prusa Mendel].
