Description
Quick educational model reverse-engineered from this picture:
It is made from scratch for display and conversation-starter at a Chemistry school event. NOT using the published functional STLs, but based on them.
It originates from this paper: https://pubs.rsc.org/en/content/articlehtml/2024/re/d4re00081a
Not meant for actual use, only for display.
For the real, functional files, check: https://github.com/Noel-Research-Group/3D-printed_UFO_Reactors
Printed with BambuLab X1C, with BambuLab blue PLA, brandless bronze PLA, transparent PLA, black PLA.
Print recommendations:
the chamber has a flat side where the "cross section" cut is, then paint supports only on big overhangs to reduce time and waste.
the tripod base does not need supports, print upside down with the flat face on the plate.
the test tube does not need supports. Use brim and start with black, then pause and change color to transparent as it goes up.
Print as many test tubes as you want.
You can also print a mirror of the chamber for the other half.
Glue the chamber to the tripod base, or make sure it rests with a leg behind it so the weight doesn't tip it over.
