Knockbox + 54mm Portafilter Holder

Don't have a place to put the portafilter for weighting coffee ?

Portafilter holder compatible with Breville Barista Express, BES870XL, BES800XL, Infuser, BES840XL, and the Duo-Temp BES810BSS.

Tips:

• Base and Rod Printed Separately, reorient the Rod to avoid using support
• ~18g of coffee for a Double Shot espresso, make sure to use the correct basket
• If you have mold growing inside the knockbox, try this alternate design https://www.printables.com/model/269463-knockbox-mk2-with-air-vents
