Drill-Driven Trimmer Spool Winding Cone
A stepped arbor for rewinding string trimmer line with a cordless drill. A 50 mm flange runs into a cone that tapers from 28 mm down to 10 mm, so it centres any spool bore from about 11 to 26 mm. An M5 hex nut (8 mm across flats) sits captive in the base. An M5 x 80 bolt with a fender washer clamps the spool down onto the cone, and you put the bolt head in the drill chuck. The flange also has six check holes for identifying 0.065–0.155 in (1.65–3.94 mm) trimmer line.
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.
