My parents' Renault Clio broke. Well, not whole car, but driver's seat regulation lever.So I have modelled the new handle in less than hour. It is very strong and fits perfectly. It looks like new now! (well, it IS new)Print the handle with not less than 0.5 fill, 0.3-0.4 mm layer, perimeters of three; element is big enough to print it full-speed of your printer. Clean-up by cutting away supply material (is is made to remove with screwdriver and knife, not very sharp to cut between layers.Hit it with the hammer on to the square-rod and voilla! Enjoy your NEW seat lever!The handle has small (0.5mm) rod-guides inside to keep it in place tightly.
