Braided ring

This is the most delicate thing that I've made.
I used (and have only ever used) a 0.4mm orifice nozzle. This braid may well be easier to make with a smaller nozzle.
Designed in Moment of Inspiration (MoI) using a script written by user bemfarmer.
I tried making it in ABS on a Robox but the result was much less satisfactory that using PETG (as shown) on a Prusa Original i3 Mk2 using Simplify3D for slicing (and thus support generation).
This needs lots of support, and a raft, and fiddly post work.
Looks nice, though...
