Modding Plexi glass tubes

Hi everyone!
A friend of mine just gave me some plexiglass tubes 13mm OD and 10mm ID.
Now I´m wondering if it exists any fittings for that size?!
Anyone....?

3mm Plexi will have to have some pretty fine threads cut in it, but that'll work, yes. You can cut a 10mm thread on the inner diameter and screw a 10mm threaded fitting into it.

 

I think he means SLI fittings, but to my knowledge they are only 12mm OD.

 

Cheapskate is right, the material in the tubes are 1,5mm thick. I dont think I can cut threads in that...
