Screw-Jack Battery Terminal Puller
A two-hook screw-jack puller that lifts stuck car battery terminal clamps. You turn a standard M5 bolt through a captured M5 nut so it presses on the post while the hooks lift the clamp, which is gentler than prying with a screwdriver. The frame is 68 × 61 × 14 mm. The hooks have a 36 mm gap between them, there is a 52 × 38 mm throat for clamps up to about 48 mm wide, and the bolt hole is 5.5 mm. It prints flat, so the pulling load stays along the layers and doesn't split them.
