Gas stove knob protectors. 1 set of 5 - color purple. One looked a little darker than the rest so I printed another one. After leaving my stove on? again. I decided I needed something to remind me to double check it when done using it, so I 3d printed these for my Whirlpool Super Capacity 465. While these are not child proof they work for me. When inserted, there is no spacing in the back which prevents the gas from being turned on. The 2 guides in the front insure that the gas is in the off position. It also holds the protectors in place. If not installed, they serve as a mental reminder that the stove is in use. Update - after posting I was asked if they came in a set of 5. Since my stove only had 4 burners I only put together as a set of 4 but if you would like 5th one just let me know. Providing I still have the same color filament I should be able to make another one. The price will go up a couple of dollars though. Update 8/20/24 - changed ad to say set of 5, left price the same.
