When I use my Presto pressure cooker, the lid lock often fails to raise when the pot is coming to pressure. This results in a significant amount of steam escaping and a lack of pressure buildup. To fix this, I often prop the lock closed with a pair of pliers. Pliers that then rust. So, I created this as a replacement.

You will absolutely need to use a plastic that can withstand the heat of the pressure cooker. PLA will simply melt and drip down the pot. I suggest nilon (PAHT). The one in the picture is PAHT CF, and it has survived a dozen rounds of heat and cool so far.
