3D printed Solar Tracker/Compass

[Stub Mandrel]

Two members of the astronomy club used to be teachers and had a favourite experiment of tracking the direction and elevation of the sun through a school day with a simple device. They asked me if I could come up with a slightly more permanent version. I came up with a 3D printed device, that incorporates a simple bubble level and compass in the base, as well as three nylon screws for levelling. Limitations of a 0.4mm nozzle  mean the horizontal (azimuth) scale is in 2-degree steps and the altitude scale is in 2.5 degree steps. I think next might be a one-piece sundial.

I like it. Has that sort of retro feel!

What filament is that light brown one you're using for the main bits?

White sprayed with matt black and over-exposed...

Any chance of the STL files, would not mind trying to print one if that if possible.

 You will need to lightly file the tapered square on top of the pointer part until it gives the fit you need.

I think teh compass is 25mm and the level is 32mm
