Herschel telescope studied the formation and evolution of stars and galaxies. Also, it observed from the far-infrared into submillimetre wavelengths, bridging the two.

I created this model on Autodesk Fusion using Herschel's photos and manuals found online.
I uploaded both the .stl and the .gcode for a Prusa mini with support.
There is also an ESA model but I found that too much of a hassle to print with an FDM printer.
