Powder Scoops - Graduated Spoons - CC Measuring Spoons

Warning: the design uses centimeters as units, so make sure to set your slicer accordingly. I disclaim all responsibility for anything you do with this data. I designed a set of graduated scoops to share with the community after downloading the Case Feeder for my Hornady LNL AP Press on thingiverse. Since I used OpenSCAD and programmed everything myself, I even learned some new skills in the process. My design was based on creating a series of volumetric scoops that get you close to the target load, then using trickle feeding to fine-tune it. The scoop capacity is measured in cubic centimeters, so I did the design in centimeters as well. This made calculating the size and shape relatively straightforward. Essentially, I used a desired capacity to calculate the dimensions of a hemisphere and cylinder that combine for the total volume. These two geometric shapes are fundamental to my design, but please let me know if you spot any math errors. My initial concept was inspired by the Lee Dippers set, which features 16 scoops with capacities measured in cubic centimeters. I've included what I call the Lee Set: a single STL file containing all the scoops that match the capacity of Lee's offerings. The Super Set is also available, consisting of 50 scoops ranging from 0.1 to 5.0 cc in increments of 0.1 cc. Each scoop is available as its own STL file if you want to print just one or two specific sizes. You can find the Lee Dippers chart here: https://leeprecision.com/cgi-data/instruct/Dippers.pdf
