The other weekend @ral has visited the and brought us the six modified fillygons needed to complete this amazing cube!

A cube made from these fits pretty snuggly into a cube made from vanilla squares!

@vimja Yup, this is possible but indeed a snug fit:

ideal edge length of large cube: 40mm;
edge length of interior volume: 40 - 2*4/2 = 36mm;
ideal edge length of small cube: 40 * 0.78122 = 31.2488mm;
bounding box edge length of small cube: 40 * 0.78122 + 2*4/2 = 35.2488mm;

You have 0.752mm to account for printer inaccuracies 🙂
