You can download the original Blender file here.
And there’s a version suitable for 3D printing available for download here.
Which you can also download from thingiverse here.
(You’ll need to scale it to fit your printer.)
If you don’t have a 3D printer yet, you can order a 3D print of the model from Shapeways here. If it’s too large/expensive you can upload and print a smaller version.
Next I’d like to commission a 3D printable model of a glass ampoule suitable for containing a small volume of air from a town such as Paris…
