1:8 Wheel Adapter for 1:10 Rc Cars

This is a wheel-adapter for 1:10 offroad Rc Cars to 1:8 scaled wheels (from 12mm to 17mm). It works for my LRP S10 Blast BX2 but i don´t know if it works for other models too. The front version just adds 1mm more space to the bearing to avoid any friction with the suspention arm. The centerring ring have to be printed with supports!
Let me know what you think.
