Summary

The Almost Impossible puzzle applied to a heart.

Instructions

Print the 4 parts and assemble (if you can!).
The openscad has a parameter that defines the spacing between the pieces. The supplied STLs were generated with a spacing of 0.25mm. Depending on your calibration (and whether you are using the buggy Slic3r version) you may need to tweak this to get the pieces to go together well. I printed using the git version of slicer that implements an equivalent of skeinforge's comb function, and the pieces fit quite snugly.

How long did it take to make?

Very cool, thanks GregFrost. My DIY printer is not the best with complicated or elaborate prints; however, this heart was very easy to print, fits together very nicely, and required next to nothing in the way of sanding or cleanup. One of the coolest and best puzzles here.

Made this yesterday, thanks! For those having trouble putting it together, you have to "set it up" with the four pieces all sitting on the very outside edge. Um.. if you look there are four small triangles that will sip inside. Try to hold all four pieces in a sort of exploded view, when they are just right the thing will pretty much snap shut on it's own.

i can't put it together ? whats the trick i can get three out of the 4 pieces but can't get the last piece in ???????????????????

Follow the ancestors that this was derived from back to the original almost impossible sphere. It has a video link for how to assemble. The same technique works for the heart.

HELP!! i need the Link for the Solution.

Very cool, like it very much. I printed this on my PP3DP printer at 0.2mm on Fine, and the parts are incredibly tight. I got it assembled and 95% put together, but I cannot seperate the pieces - haha. Damn.

Do you recommend having to sand each piece, or is a setting change able to solve this?

If the clearance could be increased that would be great, but its a press fit at the moment.

Thanks
