A parametric design for a cheap self-replicating 3D printer (reprap) that snaps together to minimize screws and non-printed parts.

Important Links:

For all platforms, you will need to have OpenSCAD installed. You can download OpenSCAD from their website at http://www.openscad.org

To insure the best fit of parts, print the slop calibrator STL file on the parent printer using the desired print settings. Then update the printer_slop variable in the config.scad file on line 130. Then proceed to generating STL files.

Under OS X, you'll need to make sure you have the Xcode command-line tools installed first. You can get them by installing Xcode from the App Store.

You shouldn't need to change the Makefile. It should set $OPENSCAD as:

OPENSCAD=/Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD

To generate the STL model files, open a terminal to the snappy-reprap directory and type:

make

Under Linux, you will need to edit the Makefile, and change $OPENSCAD to:

OPENSCAD=openscad

To generate the STL model files, open a terminal to the snappy-reprap directory and type:

make

Under Windows, you'll probably have to open and compile each *_parts.scad file individually and manually export the STL files.

You might be able to run the makefile under CygWin, if you set $OPENSCAD to something like:

OPENSCAD="/Program Files/OpenSCAD/openscad.exe"
