3D Printable Quail Feeder Design

I keep a pair of quails and would like a purpose-built feeder that I can print in PLA at home. I have a design that i can supply, however the holes are too small and the feed does not flow. I need this model copied and improved, I also need this as a editable file so I can adjust myself.

I’ll be printing on an FDM machine with a 0.4 mm nozzle, so avoid over-thin walls and include sensible tolerances for layer-line variance. Let me know if you need my exact build-plate dimensions.

Deliverables
• STL (ready to slice)
• Native CAD or editable file (Fusion 360 preferred, but any common format is fine)
• A brief note on recommended print settings for PLA—wall thickness, infill, and any supports you expect

The design is complete once the file slices error-free and the ports line up with the stated quail count.
