This is AdanA's chamfered Edge Soma Cube, but broken apart by individual pieces.

When I attempted to print AdanA's Soma cube, my filament stopped flowing at the 1 1/2 cube height, wrecking three of the pieces.

Rather than print them all out again, I separated out the individual pieces.

If anyone else needs to print just one replacement, this will save a bit of PLA/ABS.

So that I would be less likely to lose the pieces, and having just recently attained the coveted rank of junior-newbie-beginner in openSCAD, I created a box to hold the pieces.

Please note that my picture shows my first attempt which turned out to be 2 mm too high. I've fixed this, but didn't bother to print the correction for myself.

Thank you for this. I seem to have adhesion problems when I print many pieces at one time past a certain height.

Good call... I should have included the separate bits that to start with. 

Actually, the first time I tried to print it something went horribly wrong partway up: http://www.makersite.com/blog/2012/8/25/disaster-in-a-3d-printed-parthttp://www.makersite.com/blog/...  But none of them made it even above the first level.

Oh yeah! I had that problem too. In my first couple prints, the parts would detach from the platform and fall off. Looked just like your picture.

The "slurry" trick fixed it. I poured out a lake of acetone onto the heated build platform. Then I took one of my failed prints and smeared it around in the ABS, making an acetone/ABS "glue" on the platform. Wiped off a little of the excess acetone with a paper towel

Reapplied the acetone/ABS slurry between prints, and all seven prints of the full plate worked perfect after that.
