Universal Pot Lid Knob Replacement
A drop-in replacement knob for a glass or metal pot lid whose original knob has cracked, melted or gone missing: Ø46 mm heat-shield flange, 33 mm tall six-flute grip, and a Ø5.5 x 12 mm bore for an M4 brass heat-set insert so the lid's own screw threads into metal. Cored out to about 18 cm³, prints flange-down with no supports — print it in PETG or ASA, not PLA, since lid knobs sit above a hot pan.
