Charbroil grill knob.

thingiverse

So I couldn't find that specific shaped grill knob for sale anymore, and since my grill had somehow managed to burn its own knob right off (that was extremely painful), I needed a sturdy knob that I could drill out and glue onto it, because the D-Rod was no longer D-shaped. It was as if the heat had nearly completely corroded it away. This one is specifically designed not to need any additional supports. The hollowed-out areas (to save on material) are curved in shape, both internally and externally, so they won't fail. I planned to spray paint it silver to make it a perfect match, but I decided against it. It looks just fine as it is in black. I printed it out of PLA, and it seems to withstand heat well enough not to fall off.
