SAFE TEMPERATURE INDICATOR

Have you ever seen a covered pot sitting and wonder if it is still hot? With this indicator, you will be able to visually verify it is. Simply print this model with color changing filament, like this http://www.amazon.com/Gizmo-Dorks-1-75mm-Filament-Printers/dp/B00ITZO23O/ref=pd_bxgy_indust_img_y. Then, insert some 3/4" dia magnets in the base. Throw the indicator on the lid and you'll safely verify if your pot is hot.
