We now have a new enclosure, thanks to Thileepan (https://hackaday.io/TPN23).

The new enclosure looks better and feels better. Shown below is the same enclosure, 3D printed on a Makerbot Replicator 2.

There's also a circular cut-out for the temperature sensor contact. The same buttons used for the electrode connections are reversed and stuck on the temperature sensor using thermally conductive glue, that is also electrically insulating.

The new enclosure fits snugly with the body and give great electrode contact.

The Sketchup designs and the STL files will be put up on Thingiverse shortly and link will be posted to this page.
