Perfume sample holder for different diameters in different sizes

I was looking for a perfume sample holder and found this design. Unfortunately, it was too long and I only needed the 16mm, 14.3mm and 12.3mm diameters.

So I remix this model and created 3 different versions. And I know, that these aren't really 3D printer friendly designs, but I liked the look :-)

The largest holder has one row of 16mm holes, 2 rows of 14.3mm holes and 1 row of 12.3mm holes.

The mid size holder has one row of 16.1mm holes and 2 rows of 14.4mm holes. So there the samples are a little bit more loose.

And the smallest holder has 4 14.3mm holes and one 16mm hole in the center.

I printed them laying on the backside and I used PLA and PETG and both materials worked fine for me.
