With reference to Vik's glue gun idea: I have found out that you can get ABS cylindrical rods for plastic welding (e.g. here). ABS melts around 110 deg C, which means that it should go in a glue gun no problem (especially if you run the gun from a light-dimmer to allow you to adjust the temp). ABS is the plastic of choice for commercial FDM machines. Now all we have to do is to find some of the right diameter...

I just found a site that has a parametric materials search. You can specify the properties you want and it lists the materials that match. For example, say you're looking for a metal with a melting point between 50C and 100C. It'll list out a bunch of alloys, plus potassium and sodium. Might be handy for locating alternate materials for the body, circuitry and filler.
That is really useful. And it has an amazing range. I haven't been able to draw a blank on it with any non-sci-fi spec...
