Description

Upgrade your home coffee station with this sleek, durable, and functional espresso knock box. Engineered for both aesthetics and long-term utility, this design ensures that your daily coffee routine is as clean as it is satisfying.

Dimensions & Specifications

  • Footprint: 100mm x 140mm
  • Height: 150mm

Brew Capacity

With a spacious 1.5L usable internal volume, this knock box is designed for high-volume home baristas.

  • Standard Double Shots: Holds approximately 15–20 pucks before needing to be emptied.
  • Daily Use: Perfect for a household of 2–4 coffee drinkers to go several days without a trip to the bin.

Key Features

  • Modular "Snap-In" Design: Crossbar attaches securely into dedicated slots but remains fully removable and replaceable.
  • Heavy-Duty Design: Features reinforced walls to withstand repeated impacts without cracking or shifting.
  • Knocker Bar: The crossbar is positioned at the optimal height to allow for a full swing of the portafilter while keeping mess contained.
  • Compact Footprint: Engineered to save counter space while maintaining enough volume for a full day of brewing.
  • Coffee Bean Emblem: Includes a stylish, recessed coffee bean logo on the side for a premium, "barista-grade" look.
  • Easy to Clean: Rounded internal corners prevent old grounds from getting stuck, making it easy to rinse and reuse.

Maintenance & Bar Removal

The crossbar is designed for a secure, tight fit to ensure it stays in place during heavy use. To remove it for cleaning or replacement:

  • Removal Technique: Apply balanced pressure to both ends of the crossbar simultaneously. By pressing firmly on both edges at the same time, you can ease the bar vertically out of its mounting slots without bending or stressing.
  • Cleaning: Because the bar is removable, you can easily clean both the bar and the interior of the box separately.
  • Replacement: If you ever need to replace the bar due to wear, simply print a fresh one and snap it back into the vertical slots.
