These 3D-printed endcaps, made by former AKA Grand Champion kitemaker Will Sturdy, come in a variety of sizes to fit most common spars. They’re very similar to FSD endcaps, but with a rougher finish to make gripping them easier. The slot is designed so that 3/32” bungee cord will snap in and out easily (but not too easily!), making them simple to change if you’re using different size spars on the same kite. The 7.2 mm size will fit SkyShark P90 and P100 spars.
