Use a cardboard mailing tube, such as part number 0872512 from www.PaperMart.com. You can use any of the 2.5" tubes which have 0.060" wall thickness - They have inside diameter of 2.38".

You can find these tubes locally at office supply or architectural drafting supply stores. They are commonly used to store blueprints and printed circuit board layouts.
