Round Hay Rack for Guinea Pigs or Rabbits

thingiverse

This round hay rack was a from-scratch design in Fusion 360. I'm not calling it a remix as it is a completely original design, but I would like to acknowledge both https://www.thingiverse.com/thing:3966189 (@CorrieD) and https://www.thingiverse.com/thing:4244943 (@GGREINER) from which I drew inspiration. Compared to those models, my version is in 2 pieces. The base and bars prints as one piece and the lid prints as the second piece (print hole-side-up). I have tapered the tops of the bars and the holes just slightly for an easier fit given the large tolerances needed by some printers. I have hollowed out the base to save on filament and I have added chamfers to the bottom of the bars for extra strength. I have used an 8-bar design so that the guinea pigs have enough room to get their noses in to grab the hay but not their whole heads. One of ours had a nasty incident with a grass seed getting stuck in her eye so it's not great to let them get their whole head in there. Original Fusion 360 design is available at https://a360.co/3gLNe4a should you wish to change any aspect of the design. If you do remix it, please drop me a comment as I'd love to see your work. The design fits easily on the bed of an Ender 3 printer even when a skirt is used and is about two thirds of the height. Overall dimensions of the base (the largest part) are: 150mm diameter by 166 mm tall. My design is completely free to use without restriction. Have fun and I hope your guinea pigs like it. COVID-19 has meant that I have some time to work on designs and projects but it has also meant that my income has fallen off a cliff due to lost business, so if you can afford to send me even a modest tip, I would be most grateful. Every little helps!
