This is a clone of the type of tool you'll see sold at some auto shops or on amazon. I needed to remove the window crank on my '95 S10. Worked great!

Takes an hour to print with PETG. Would definitely print faster with PLA, and it's worth a try if that's all you have. The key stress points are pretty thick and the amount of pressure exerted onto the spring to remove it is not actually that great. You're more likely to damage softer plastic as you poke around trying to figure out which way the spring is oriented.

Anyway, this saved me a trip or waiting for a delivery. Hope it helps you too!
