what you get is a super fine crafted wheel with simulated lugnuts and a set of hubcaps for the Front- and Rearaxle, a beadlock ring and a ring for the inside of the tire. The Beadlock Ring can be screwed to the wheel with 3x12mm screws with plastic thread.Printing:I recommend PLA for printing. The screws will hold very good in this material. You can use the standard settings for PLA.
