My Renault Clio 1.2 2000 all front seat levers broke. The levers are very poorly designed and break easily so I designed stronger ones. This lever/handle has a hole for a small M5 nut and bolt so you can be sure the handle won't fall off. I actually prefer not to use the bolt so I can take the handle off quickly and use it on another seat. The settings I used : Layer height: 0.18 Walls: 0.8 Fill: 60
