I just finished a paper model of a new Stewart toroid I discovered a while ago. This has all regular faces and is non-self-intersecting, with genus 41. All edges of the convex hull are also edges of the model (another one of Stewart's criteria).

See my page about it at https://www.software3d.com/WebbToroid.php

Another great model, Rob. What's your opinion of "Adventures among the Toroids" ?

It's a fun investigation of something similar to Johnson solids but with one or two restrictions removed. Been a long time since I read it though.

Great model! Pretty paper, pretty colours, precise work.

Are the dodecagons and the decagons of the convex hull regular?

Thanks Ulrich. No, if they were both regular it would be a new Johnson solid! The decagons are regular, but the dodecagons are not.
