So I made the beadlock rings for the 3DSets rancher wheels to prevent tires from slipping of the rim. In addition, you can add 70g weights to each of the ring to lower the center of gravity. 

To add the extra weight, I used these Pb (14x5g) weights: https://bvbcz.cz/p35724-706h-40g-pb-8x5g-samolepici-zavazi-moto-hofmann?gclid=Cj0KCQjw1rqkBhCTARIsAAHz7K2tBDUE-ipZI3UqltzlT15lxhpr3w1TJKI_-8tMPIfXJY-wN_u-o5saAvwhEALw_wcB

I am providing STL/IPT, so you are free to remix these rings to fit different weights/wheels if you want to. Hope I’ve helped you.
