Three-Screw Self-Centring BBQ Grill Knob
A universal replacement burner knob for gas grills where the original has cracked in the sun. It is 55 mm across and 34 mm tall, with a pointer fin on the front. It has a 9 mm stem bore and three M4 set screws at 120° in M4 heat-set inserts (5.5 mm bores), so it centres itself on round or D-flat valve stems from about 5 to 8 mm instead of needing one exact OEM fit. Holes in the skirt give a soldering iron and hex key access and let rain drain out. Print it in PETG or ASA for outdoor heat and UV.
