Summary

Thing: https://www.thingiverse.com/thing:579458 Looks great.
I enlarged it and I split it into two parts + holes and added pegs (for getting the parts together.)
Now it can be print without support even if enlarged more.

Just as David wrote : it Turns exceptionally well !!!!

Post-Printing

Glue maybe needed to put the parts together, depending on the material.
There were cases where I was able to simply push the two parts together, and there was also a case that I had to sand the holes a bit in order to get a fit.
