CS7.2 · Open-source · 3D-printed
The AI Case Sorter photographs every case, reads the headstamp with a trained AI model, and drops it into the right bin. You build it yourself from printed parts and an easy electronics kit.
CS7.2 in action
How it works
Cases drop through the feed tube into a stepper-driven feed wheel that indexes them one at a time.
A camera under an LED light ring takes an evenly lit photo of the case head.
The AI Headstamp Sorter app on your PC reads the headstamp with a model you can train on your own brass.
A homed stepper swings the drop tube to the matching bin and releases the case. Then the next one comes through.
CS7.2 is built from five assemblies. A dedicated electronics board replaces the hand wiring and soldering that CS7.1 needed.

Everything is documented in the GitHub repo. Work through these in order.
Pick the Complete kit if you’re starting from scratch and building a single machine. It’s usually the cheapest way to go. Pick Essentials if you’d rather source the common hardware yourself from the parts list.
Each “EZ Build” zip contains only the models your kit needs, so you print everything in it. The printing guide lists recommended filaments and settings.
Upgrading from CS7.1? You can reuse the light shade, feed tubes, feed bracket, feed wheels, drop tube, drive gear, sorting bins and more. See the instructions for the full list.
Follow the PDF guide for each assembly, and watch the matching build video alongside it.
