This knot was created by exporting a model from [KnotPlot](http://www.knotplot.com/) and then adding extrusions to each mesh face in [TopMod](https://www.viz.tamu.edu/faculty/ergun/research/topology/), then printed with an Ultimaker 3 using dissolvable PVA supports (the second picture shows the newly-printed knot in a bucket being filled with water).

Inspiration and KnotPlot model are credited by my student Jonathan Gerhard; you can read about his related project on his blog Mathematical ADD here: [The Perko Praxinoscope and the Shrikhande Graph](https://mathematicaladd.wordpress.com/2017/03/20/the-perko-praxinoscope-and-the-shrikhande-graph/).

For information about how this model was designed and 3D printed in PLA with dissolvable PVA supports, see our article at Hacktastic: [Giant Spiky Perko Knot](http://mathgrrl.com/hacktastic/?p=4401&preview=true).

**UPDATE: Follow along with a reprint of this model in PLA with breakaway supports at our new article at Hacktastic: [Perko
