So far I've tested the 62mm versions, and they don't fit - not without alot of force and some screwing around. The 60mm version is on the printer as we speak and I hope to test this shortly. Designed for mag rim from the brand name "Speedy Wheels" - specifically their "Cobalt" edition. But to my understanding many of their rims use the same hub diameter. I have included the inventor IPT files if you wish to emboss your own design, or if you can't or don't know how, leave a comment and we can arrange to assist you. http://www.speedywheels.com.au/SpeedyWheels14.pdf See page 6, the cobalt 2 is almost exactly the same.
