3D model description

https://youtu.be/h6VtL_donnw

The print is complete and pre-supported, but it's still a work in progress - the inner hub sections need a rework for printing without breakages, and some of the outer sections have "hacked-in" index lettering.

also at some point I need to make some instructions :) for now just realise that the segment indexes are counted in an anticlockwise direction. So when you're looking at the outside of a segment, the lower number segment is on the left and higher number on the right - the numbers are the wrong way around when you're looking at them.

Of course to make the animation work you'll need a strobe source, and I happen to make 3D Zoetrope kits exactly like the one in the video - see 4-mation.co.uk

My machines have enough strobe brightness to work in moderate ambient light (don't need a dark room) and also as per the video you can control the strobe brightness and colour.

I used games workshop contrast paint apothecary grey darkened with some black ink and some nuln oil to paint it - although it took an entire pot plus a substantial portion of nuln oil - so you might consider mixing your own contrast paint - eg https://youtu.be/VU0rc0EOOys?t=425
