Carbon Fiber Tube
This carbon fiber tube measures 0.47 inch / 12mm ID, 0.55 inch / 14mm OD, and 8.66 inch / 220mm long. At this low price they can be excluded from the Cost Accounting Worksheet. Look up safety guidelines if your going to cut or drill carbon fiber.
ProTip - some 3d printers can use carbon fiber filled filament. 3D print fittings and glue the tubes in place to make a structure. Give your robot a big advantage with the highest strength to weight material used in FRC!
