This is by far one of the most cost saving 3D printed repairs I have done. I sadly dont have any photos and have since sold the car but image a pathetic lever with a tiny cross section that must support all the force of you pulling in it because your battery has run flat and you need a jump. It took 2 iterations to get an optimal fit but I got it and printed it in ABS then acetone vapour polished it so that one cannot even tell its a home made replacement part. This saved me about USD 150 (my exchange rate is horrid)
