3d printable feeder

3D printable automatic pet feeder. Design: simple geometric shapes (cubes, cylinders, cones). Style resembles a manual meat grinder. Components: Top hopper (inverted pyramid) → connects to horizontal tube with auger inside. Tube ends with a bowl where food drops. Auger (helical screw) is removable and secured only with 2–4 small bolts (no other fasteners elsewhere). All other joints: snap‑fits, bayonet mounts, dovetails, or friction pins. Model split into parts for assembly/disassembly without glue. Output: separate STL files. No supports required. There must be technical holes in the model. There should not be a meat grinder nozzle.
