Breville Barista Express Single Dose Hopper 2 Piece Bellow

I really like the original design, but I felt that vase mode would be the ideal way to print the bellow. With that in mind, I designed the bellow specifically for vase mode printing. I used a 0.8mm nozzle, but if you have a 0.4mm or 0.6mm nozzle, you can simply adjust your extrusion width to 0.8mm to print it successfully.

The end piece is designed for a snug fit, and I printed mine in PLA. I noticed that in the original model, the end that fits inside the hopper was the first part to fail. To improve durability, you can print the bellow in TPU for flexibility while using PLA or another rigid plastic for the end/adapter piece.
