Here is a simple design for a Super Feeder, suitable for cats, dogs or fish, available at http://www.super-feed.com/. The design can be customized using an SCAD file. Print Settings: Printer Brand: RepRap Printer Model: Prusa i3 Rafts: No Raft Needed Supports: None Required Resolution: 0.2mm Layer Thickness Infill Density: 15% Notes: If you experience under-extrusion issues, try enabling Slic3r's automatic speed function. It worked well for me!
