You need to use a slice modifier in any 3d software and then normal align the bases to be flat on the build plate. But make sure you close and weld any holes.

    DrSmiley,

    I take a cut line in the part that would make it easy to put it together it does not have to be in the center, what works best for your print.

    I usually extrude cut thru the center of the part to remove the other half in SW,

    make a STL file, then move the cutting tool in SW to the other side and remove that material and make a STL file. You can if you want place both parts on the print bed area and slide one off the bed do the slicing, save off the Gcode as the left side then slide that one off the bed and bring the other side onto the bed and save the Gcode under a different name. If you are going to glue it together on the back side create gluing tabs or you can use the brim material to use as gluing tabs.

    what type of glue all depend on what material you are printing with.

    hope this helps

    Instructions on cutting AnyThing.stl into parts.

    The most general way to do this for any Thing.stl file

    install OpenSCAD (its free and works on most platforms)

    commands used:

    import();

    translate();

    cube();

    functions used:

    difference(){}

    code looks like this

    difference(){

    import("/PathToThing/TheThing.stl");

    translate([x,y,z])cube([x,y,z]);

    }

    cube - x,y,z are adjusted to make a cube that covers TheThing

    translate - x,y.z are adjusted to move the cube over the part of TheThing you do not want in the HalfOfThing.stl

    iterate adjusting x,y,z values until your are pleased with the cut.

    then render and export to your HalfOfThing.stl file

    difference(){   import("/PathToThing/TheThing.stl");   translate([x,y,z])cube([x,y,z]);}

     

     

    That's cool.  I use OpenSCAD sometimes.  I didn't know about the import function.  I might do that next time I need to edit an STL.

    Complicated answers given here... :) Just sketch a line where you want the model to be split and then add an Extruded Cut feature. In the options, check "Thin Feature" and set the thickness to something very thin like 0.1mm (this will be removed from your model). Select "Through all" for both directions and confirm. You'll be asked which bodies to keep, leave it at the default "All bodies" and you're done.
