UPDATE 4/21/18: Version 4 released. I opened up some tolerances to help with fit after painting. This version still needs test printed and painted but my printers are all currently busy. If anyone prints these before I get a chance, please let me know in the comments if it helped or if it still needs more adjusting. I also made the oring groove deeper to help it fit in a can once the oring is on. I thinned out the vials a bit too so there should be a better fit if you go the route of printing them instead of buying them.
Thanks for all the feedback along the way.
old status: ((This is still a work in progress but I wanted to get it uploaded for testing and feedback.))
Update: New and improved parts added for the functional version (labeled new parts V3). Fixed the static model "top cylinder" so the threads at the top print correctly now. Added the details in the description for the vial labels.

I modeled this Jurassic Park cryo can with dimensions from the RPF reproduction that many people have. I added the proper profile to replicate the bottom of an actual Barbasol can. This will fit inside of a Barbasol can and I will upload more information about cutting the can later.
There are two versions of the files here. One for a static display and the second for a functional piece.

If you print the functional version, I recommend increasing the infill for added strength. Especially on the "tall cylinder" and "bottom thin ring".

I am still sourcing a spring so depending on what I find, I may modify the "tall cylinder" part. I may add set screw holes as well.

The proper vials can be found on eBay, though I did add a model as a placeholder for those who want to print it. On eBay: Fisherbrand Sterile 1.5 ml Microcentrifuge Tubes with Screw Caps http://m.ebay.com/itm/Fisherbrand-Sterile-1-5-ml-Microcentrifuge-Tubes-with-Screw-Caps-02-681-373-/182555772490?hash=item2a812c064a%3Ag%3AATkAAOSw03lY4wPp&_trkparms=pageci%253Af44d056c-66ed-11e7-9c46-74dbd180bd29%257Cparentrq%253A365f0c0815d0abc59fdf7df1ffee1e7a%257Ciid%253A1

I included the model for the black ring but I used a found rubber o-ring that we had at work.

here is the vial info:
TC-2.050
TC-2.050
DL-2.01
TR-1.0
VR-1.0
VR-2.0
ST-2.032
PR-3.01
GA-2.035
MT-1.02
3mm tall leters, black lettering on white background

I ordered an assortment of springs from Amazon and used two 35mm long, 9mm diameter compression springs from the set.

For anyone interested, I did a time lapse screen capture of the bulk of the modeling. https://youtu.be/WmA8DK3L9es
And here is a video of the functioning prototype, printed from the V3 models here.
