I simply pulled the knob off in the store & shoved the rest of the stove up my butt, later at home I printed the missing knob. It's a simple life-hack, basically everyone is doing it.
I hate that as a society it is somehow ok to steal for your convenience. Its the same thing with lots of other things as well. Don't you just love it when you buy a product only to get home and find half of it was stolen?
