These are just rubber blocks with a T shaped cut in them. Why don't you make
your own? Or if your University has an engineering or physics department ask on
of their machine shops to make you some. How many do you need?

Very nice, but they are a bit pricey.

Phil Davis' BTZS tubes would be an option and can be made from plumbing supplies
at your local hardware store, or there is a commercial source for these as well.
The BTZS tubes have caps on the ends of the tubes. Another system, I don't
remember the name right off hand, just uses open ended tubes.
Hope this helps.
