Sized exactly to the MakerBot Replicator Mini's build dimensions of 10x10x12.5 cm, this bong has a unique "Cubism" design. It gives a nod to the late great Picasso with it's rectilinear and angular shape. I was giggling the whole time I designed this bong! Simple, elegant, and rather unusual, folks may not even realize that it's a bong when they see it. Great for stealth. It has a carburetor and a special diffuser tube that I created. Accepting standard bong parts including grommet, down tube, and bowl, this bong is very practical even in the low temperature material of PLA. Check out the cross-sectioned STL file with Thingiview to see the internals. Fun! The OpenSCAD file is parameterized so you can resize it by changing the outside dimensions vector. It uses intersection(){} with a build chamber primitive to ensure that not one iota of it exceeds the precise working space of the MakerBot Replicator Mini (can you tell I plan to buy a Mini?) There are two switches that you can set to either "true" or "false". One creates a carburetor just below the mouth hole if true, and the other does a cross-sectional removal of the right half of the bong (positive x direction) so we can see inside and check out the details of the diffuser tube.
