As for the test tube ... Humm ... I don't think the "pyrex" glass thickness will allow you to wind a resistor using AWG 20 "Ni Cr" wire .... this material is very springy stuff and you must apply a lot of pressure to get it winded, so I wouldn't recommend it.
There is a piece of 32mm that was a scrap that we found the ends are melted in as normal but it isn't totally perfect it's "exactly" the same material as mine and Aarons prototype resistor and the same size. If you would like it, I would only charge you shipping, if you need a photo or something we can talk in the PM's.
