Gi Joe Vamp Modified Rims for axle.
This is a modified rim for SparkBibo's GI Joe VAMP and should also work on the VAMP MKII and Cobra Stinger. I have not tested it on the latter two. I loved the VAMP designed by SparkBibo but when I printed it and found the wheel did not rotate freely around the axle. I modified the rim by creating a small groove so when the rim is placed on the axle it rotates freely and stays on the axle. The rim will snap in place.
