This is a remix.
I didn't design this nice model, I've only converted it in STL and added a base.
The original model and author here
https://sketchfab.com/3d-models/spiral-a4e84079db884dddbc2e980b44ce8cfd
Printed @0.15mm with PLA: Prusament Mystic Brown (base), and Prusament Vive la Bronze (spiral)
Took great advantage using PrusaSlicer the function Paint-on support/Highlight overang by angle: 30°
Then activate the snug supports, and Support: print only enforcers
3mf file with my settings included.
Happy printing! :)
