Here is Ketracel white vial used by Jem'Hadar in Star Trek Deep Space 9. I haven't test printed it yet so if you do print it please let me know how it come out.
Update 03/03/2019 - I test printed it and model needed scaling a little bit. Now everything prints OK and fits perfectly.
Physics, 3D printing, Programming, Astronomy and Sci-fi - that's me \//
