Dado Box (for use with openscad CSG ops) (Q42225)

A repeatable Dado Box. One way to look at it is that this box can stack with itself on any surface. I use a loop like this to slice up big models in openscad: for(ix=[0:2]) { for(iy=[0:2]) { intersection() { translate([ix * dadoSize, iy * dadoSize, 0]) placeMyModel(); translate([ix * boxSize + ix * dadoSize), iy * boxSize + iy * boxSize, boxSize / 2]) translate([baseOffsetX, baseOffsetY, baseOffsetZ]) placeDadoBox(boxSize, dadoSize); } } } } } This will seperate a big model into many smaller models that fit together like puzzle pieces. My 2-D dado box (take off all the rotate([0, 90, 0]) shapes) works very well, is printable, and can be slid together easily... but requires a little bit of clamping and gluing to get a nice stable construction out of. The 3-D dado box however, not so much. You can't slide two neighboring pieces together without a weird diagonal slide, and the dado box itself isn't printable. I'm hoping someone wants to make a derivative of this that's printable, and I'm also hoping that if the box itself is printable, that means the items you make with it P.S. I actually am a veteran POVRay user, so I didn't need much of the tutorials to understand how OpenSCAD works... but because I have been reading the tutorials, and they are, in fact, awesome... I decided to tag it with openscadtutorial anyways.
