samolot,

One of the cleanest and and best looking ways is to for example buy some 4-40 all thread rod and buy the Mid West Carbon Fiber tube that fits it the best. Cut the 4-40 rod to length, cut the CF tube about 1 1/2" shorter than the 4-40 rod. Slip the CF tube over the 4-40 rod and secure it on both ends with 4-40 nut. Now add your ball links are whatever you choice to use to both ends of the rod. Add a drop of CA on each nut so they wont come loose.
