Powder Scoops - Graduated Spoons - CC Measuring Spoons

Warning: the design is in centimeters, please set the input units on your slicer. Also I am not responsible for anything you do with this data.

I needed a set of graduated scoops. Since I downloaded the Case Feeder for my Hornady LNL AP Press here on thingiverse, I thought I'd give back by designing a set of scoops for the community. I used OpenSCAD and did all of the programming myself. I even learned a couple new things in the process.

The basis of this design was to create a series of volumetric scoops to get in the ballpark of a load. Then trickle feeding in the difference. The scoop capacity is in cubic centimeters, therefore the design was also done in centimeters. This made calculating the size of the scoop relatively easy. Essentially I used a desired capacity to calculate the size and shape of a hemisphere and cylinder that sits on top of it. These two primitives' combined volume is equal to the desired capacity. Also, the actual capacity may vary slightly with printer, material, temperature, and other factors.

I initially based my concept off of the Lee Dippers set, which has 16 scoops measured in cubic centimeters.

I have included what I called the Lee Set. A single STL with all of the scoops that match the capacity of the scoops that Lee provides.

I also included what I called the Super Set which is a set of 50 scoops from 0.1 to 5.0 cc in 0.1 cc increments.

And there is also each scoop in its own STL, in case you want to get specific and just print one or two.

10/02/21 I updated the code a little bit to try to make the Customizer work. It is now working within OpenSCAD, so you can generate any scoop you want using that software still. Now you can create them using parameters, instead of having to code. I wanted to make the thingiverse customizer work, but there seems to be a problem and no way to debug it. I left the original code sheet there for reference, but the new one is at the top of the list.
