My wife broke the knob on the old crockpot from my great grandma. I believe this crockpot is from the 80s. Over the years it has got used a lot, ever since I was a child.

I printed this out of Basic ABS from Flashforge, using a Flashforge AD5M Pro. I printed with 50% infill, no supports, with a 1 layer raft at 0.1mm. 

Inside the knob is designed to be a press fit, so it may require a little filing or cleaning.
