Inspired by MeltIn forma model, i made from scratch a version to print without AMS. I included a small tolerance print test, just chopping the original model, so you can check if you need to adjust the tolerances before printing the whole thing. The model is cut by half, so just print twice each part and then glue them. Pins are mandatory for a nice alignment of both halfs. It is sturdy once assembled, but there's some thin parts, so treat it nicely before assembly. A total of 8 pins are needed for the print.

Use colors as you like, I used Shiny Gold, Plain Silver and Cyan.

Any advice for improvement is welcome.

Update 1:
Added another 3mf file, with both blue parts included, ready to print with AMS like systems. Please choose the correct version to print. I'm sorry, @donutmelwater, for the problem it caused, and thank you for bringing it up. The AMS version will still be split into two, to avoid supports and allow for a nice surface finish.
