This case was designed for soft tip darts with slim flights. There is enough storage in this case for one set of darts and it has two additional storage channels for extra barrels, shafts, or tips. The case was designed for the darts that I throw. My darts have "micro tips" that are about 0.75" in length (not counting the threads), 0.25" diameter barrel (inside dimension of case shafts are designed at 8mm), 3" barrel + shaft length, and slim flights (1.75" long and 1" wide), and an overall length of about 5 inches when fully assembled. I can modify the current design to fit your soft tip or steel dart dimensions. I have many iterations of this case already designed with varying degrees of storage capacity. So if you are looking for something similar to what is shown here, but this case isn't exactly what you want, send me a message. I can design it for you.
