Based on the sources of the 3D printed Debian bottle, that onovy brought to debconf19.
Main modifications -
- has some hollowness
- smaller, so quicker to print
- added a swirl on a stick, so together looks like the complete official logo

The 3mf files are example prusa slicer files using organic supports.
Probably you need to modify them to match your printer and the filament you use.
Failing to do so might lead to either too high or too low temperature used for printing,
what you might want to avoid :D

Printing the bottle with the material PET led to a very sticky result,
that took a while and lot of isopropanol.
Also have printed the same model with PETG without supports,
what on the one hand made it very easily removable,
on the other hand it looked a bit ugly on the bottom half.
(On the jpeg, the bottle on the most right end was printed without supports)

The flipped version of the swirl is, as sometimes one side is printed looking nicer,
depending, if it's up or down the bed
