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.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Screw-Tension Band Clamp 60-68 mm
A T-bolt style band clamp that draws down evenly on anything 60–68 mm OD (2" PVC at 60.3 mm, 63 mm PE pipe, 2.5" dust hose, pond and irrigation hose) using one M5 x 50 bolt and a captured M5 nut in a 5.7 mm across-flats hex pocket. The 14 mm wide, 2.8 mm thick band has a smooth 68 mm bore with no screw slots or sharp tail, so it spreads load without gouging silicone hose the way an oversized worm-drive clamp does; thickened 9 mm end bosses keep the clamping pressure even and the whole 81 x 74 x 14 mm part prints flat with the hoop load in the XY plane.
