Ursa major astronomy card

This is my model “ursa major astronomy card”… It's a great astronomy model designed for the contest “Space explorations”.

I made this model in freeCAD on my own… I used stellarium to position stars on exact places.

I printed the model in two colours (black and white) and there's no need to use support… Anyway, I like the model and please support it.

Good luck with the print!
