This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Hmm.
I do quite a bit of parametric modelling and I see how something like this could be made. Find the angles of the sun at specific times, project planes at a fixed distance and angle matching around your cylinder, sketch the time number you want on each plane with a fixed pitch and then project-cut back through the cylinder. Would be a pain in the ass though. And a pretty tough 3d print without soluble supports, given all those tiny tiny interior walls and cavities.
Nope, I printed this with a poorly calibrated FDM printer and it still worked great.
That's my secret... All of my printers are poorly calibrated
