[3D PRINTED] Breville Barista Express/Touch/Pro Single Dose Hopper

This single dose hopper replaces the stock hopper with a much smaller, low profile design that holds 18-20g of beans. The stock hopper has 2 locking pins to hold it in place, one of which activates a safety switch. This feature, which was challenging to duplicate, is implemented in this design. The bean feeder chute extends all the way down to the grinder, preventing beans from falling into the voids around the burr grinder.

Two hopper lid designs are provided, the first is a simple flat lid. The second is a bellow. This is intended to blast any remaining grounds out of the grinder into the portafilter.

This hopper should work on all Breville machines that use the SP0001570 Bean Hopper, namely the below models:
1) Barista Express BES870
2) Barista Touch BES880
3) Barista Pro BES878

[How to Install]
1)Clean up the 2 hopper pins and ensure they slide freely in their respective slots in the hopper base. Also ensure the pins can move freely on the spirals in the feeder bottom.
2) The feeder assembly has 3 parts, the bottom, top and extender.
3) Check the fit between the 3 feeder parts, clean up where necessary
4) Assemble the 3 feeder parts using your choice of adhesive. I used regular super glue.
5) Clean up extra adhesive around the joints if necessary.
6) Clean up the holes and test fit the 2 M3x6mm screws that go into the alignment tabs on the sides of the hopper base. The screws should only extend about 2-3mm into the hopper base and the heads should not project from the 2 alignment tabs.
7) Back out the screws so they don't project into the hopper base interior before proceeding.
8) Ensure the feeder assembly rotates freely in the hopper base.
9) Insert the 2 hopper locking pins into the hopper base in their respective slots. Make sure both pins are all the way out.
10) Align the spiral with the slots in the locking pins and insert the feeder assembly into the hopper base. This part may be a little fiddly to get right
11) Gently rotate the feeder assembly using the knurled knob. It should rotate 1/4 turn from the locking pins being fully extended to being all the way retracted.
12) GENTLY screw in the 2 M3x6mm screws to retain the feeder assembly in the hopper base. If the feeder doesn't rotate anymore, back out the screws slightly.
13) Remove the stock hopper as shown in the user manual.
14) Rotate the knurled knob on the feeder assembly until the locking pins are fully retracted.
15) Line up the alignment tabs on the hopper base with the espresso machine slots
16) Fully insert the complete assembly
17) GENTLY turned the knurled knob to lock the assembly into place
18) DONE!
