it is pretty similar to an old nautical barometer. Because I can't afford that I did it in 3d print.
I made the whole gauge in 3d print. I'm still working on it but it is pretty similar. Based on images I made it in 6inches diameter.
I'm just asking, because I saw some on eBay in different sizes. Looks nice fir my display. But I would prefer one with the correct needle. Is it also possible to print the needle in 3D?
I made one in 3d but I did print it yet, I'm trying to adjust the measurements to make it as accurate as possible.
(It looks better than the screenshot )
