Sierpinski N3 sprued.

This is a remix of Zencoal's Sierpinski Cube. It is pre-sprued and ready to cast for those of you ambitious enough to try. Print without support, 2 shells, 5%, infill… tolerance can be adjusted in the SCAD file if your printer has different settings.
Attached is a video of the Sierpinski quench after casting.
