A couple of days ago, a friend sent me a link to one of the coolest things I've seen in ages: @ElminsCosplay's 'Mobius Gears'. Just follow that gear chain round with your eyes. Wow! Kudos to that Homo Sapien...
I loved it so much, I thought I'd have a crack at modelling it up. I don't know anything about gears, so I decided my version would use 'friction wheels' (e.g. the wheel from a scooter or in-line skate) to keep things simple. I built my model in OpenSCAD in case it's of interest to anyone out there: MobiusGears.scad.
With reference to the image, below, my design has four components: the ball-race (orange), which is made as a single piece; a set of poles (green) that elevate the ball-race above a circular base (grey); the friction wheels (yellow).
I've not actually printed/built my version (I'd love to hear from anyone who has a go!) - I'm not even sure how you'd print the ball-race without spending several years cleaning off support material...
