NormalCurveGenerator

01-28-2021 Update. I have finally made a print of NormalCurveGenerator (NCG) and it unfortunately does not work too well, or dishes I have not found the right sand for it. The beautiful black sand I had found stuck to the side of the NCG and was almost impossible to shake out. I do not know at this time if it is the sand, the plastic, the design or all the parts that are the problem. I will of course come back with more when I know more. This is a physical visualization on the probability calculation of normal distribution / curve of normal distribution. It is used in an incredible number of places, e.g. in the industrial realm where one must have a measured quantity. The bottle "NDG_Part_1.stl" must be printed in transparent plastic so that you can see the distribution of the contents of the bottle. You start by filling sand down through the funnel until a clear curve can be seen in the bottle. Now put on the lid "NDG_Part_2.stl". Here I have been a smuggling dog because I have not made a thread, so here you must either glue it with sec glue, or use tape. It is now put in the holder and you can now turn 180 ° and watch the sand run to bake or make a Normal Curve. You can read more about the topic on Wikipedia: https://en.wikipedia.org/wiki/Normal_distribution At the moment I do not know for sure if it works as I have not made a print yet. I will come with pictures and update as soon as I have made the first print. Have fun!
