The first prototype was made more than a year ago - and so much has changed since then.
We've spent so much money designing and prototyping the ColdCan that I've been looking for smart alternatives to our approach. The 3d printer is working and I've started using molds to handle the rubber gaskets on the prototypes. So, now, I'm able to run the 3d printer for the bodies and pour the rubber with a compression fit for the gaskets.
The end result is a solid prototype with lid, body, Cryogel interior, and rubber rings. Not bad - right?
Here are some pics to see for yourself.
