Use a black backer board ( you can spray paint some pc board with black spray paint ) then use black thread - I use black silk suture thread to support them. Almost invisible and very strong but with some give if needed.

I would possibly use a piece of rubber tube where you can place the tube in, just like a few kits place their colon tube
See https://www.nocrotec.com/shop/images/content/colon-02.jpg
Another possible solution would be to use a slotted-pc board and then glue in the whole tube base with kind of silicon glue (sticky but flexible).
Another version would be this:

I've got everything working on the bench, but now it's time to get things mounted for display! I'd like to have the tubes stand vertically next to each other. I'm looking for suggestions on how to securely mount these tubes. If possible, I would prefer to mount at the bottom only so that the top of the tubes are free and clear.
