Hello, For a bit of fun here's a holiday challenge. Can you model a Möbius strip that's about 10m long, 200mm wide and extruded 1000mm or of similar proportions? It has to have a thickness.   Some of you might yawn at this no doubt, and it is dependant on the Deform tool of course. It's actually quite hard to bend so that there is no visible join. I will post my solution in due course.         Mobius spin.mp4
