Adjustable Coffee Brew Time Tag

We have 3 coffee air pots at my work and its always Russian Roulette on whether you're getting fresh or possibly even from the previous day. I printed the everything at .2 layer height on the first run and next one I will do the dials at .1 to get a little better definition in the numbers. I put a little bit of glue in each dial hole just to add a bit of friction. I went over the numbers and text with a black sharpie and it worked pretty decent. The whole thing is made to assemble and use 1.75mm
