Escher knots

thingiverse

Several versions of the large tube knot from the Escher woodcut are showcased here, with a closer resemblance to the artwork than my previous attempts. Unfortunately, I was unable to achieve clean prints, as the bottom portion turned out messy despite a fine top. It's possible that someone may have better results using an SLA printer. UPDATE: 12/04/2018 - A retry of the solid knot with one flat side against the print bed and supports holding up the remainder resulted in much better outcomes. I've updated the STLs to include rotated models, identical to previous versions but with a change in orientation. Both solid-tube and hollow-tube versions are included, requiring users to mirror the STL for correct handedness matching with the original artwork.
