The base is made in Prusaslicer and the G-code is a custom Ender 3 profile. I guess best thing would be to open the .3mf file in Prusaslicer, tweak some things, and print, but I'm uploading the tower alone as a STL (which doesn't include the base made in Prusaslicer).

Let me know if is working ok, I'm willing to edit it a little if necessary.

Supports: Is up to you, there are some overhangs here and there but I just print it without supports and sand it a little if needed. This webby style is forgiving!
