I needed a very specific sized purge chute and bin to fit my specific setup so I designed this. It's only 55mm from the edge of the printer to the outside edge of the chute which fits in between the printer and the back edge of this Ikea dresser, but it should work just fine for anyone that wants a slimmer bin. I intentionally kept the ramp solid to add a little weight to keep it from moving around on its own, but it still used very little material.
