This is used to remember set flame. I use it when i want to heat up the oven between pizzas, and then when i want to cook them, to set it easily to low flame without looking in the oven and being precise. You just find low flame once when oven is lit, tighten the wing nut and you have it ready :)
There are 2 version of the file.
For each version you will need M8 wing nut, and M5 bolt (60mm) and m5 nut.
I inserted the M5 bolt from the underside (there is premade hole in the oven to get access) in a hole next to the dial (also premade). So no drilling or modding is necessary. Then put m5 nut from outside, tighten and use some glue for nut not to get loose.
And for m8 bolt insert version you will need m8x30 hex bolt. If fit is not tight enough, you can glue it in place.
I recommend printing with petg, abs or asa because of the radiating heat from the oven.
