This is a replacement grill knob for a Master Forge Grill. You will need to have the square metal piece that couples this to the knob stem. I printed these in PLA and have not had any issues with them at all (the heat from the grill in the knob area isn't hot enough to mess them up). When printing is complete you will have to use a hammer to pound the square metal piece in. Just make sure you have the hole lined up for the set screw before pounding it in.

For reference, in my photo the knob on the far right is an original knob, the four on the left are Hatchbox Silver PLA
