The Square Espresso Knock Box with Oak Knock Bar
Each KNOCDIC® knock box is made to order using high-precision 3D printing, so subtle texture and fine layer lines are normal.Colours and natural oak grain may vary slightly from piece to piece.
Why we 3D print our products →The Square Espresso Knock Box is a compact, stylish coffee grounds bin designed for home baristas who want a cleaner, more organised espresso setup. Made using high-precision 3D printing and finished with a smooth oak wooden knock bar, it gives you a simple way to knock out used espresso pucks without mess.
Perfect for Sage/Breville machines, manual espresso setups, and small kitchen coffee stations, this knock box is available in three practical capacities: 3–5 shots, 8–10 shots, and 14–16 shots. Choose a small size for daily home use, a medium size for shared coffee routines, or a large size for heavier espresso drinkers.
The body is made from eco-friendly plant-based PLA, while the oak knock bar is sanded and hand-varnished for a smooth natural finish. The box is also coated with a durable, water-resistant layer for everyday use.

FAQs
Please read our FAQs page to find out more.
What materials are your coffee tools made from?
All our products are made using PLA, a plant-based, biodegradable plastic that is more eco-friendly than traditional petroleum-based plastics. We chose PLA not only for its sustainability but also for its strength, finish, and vibrant colour options.
Are 3D printed tools durable enough for daily use?
Yes! Our products are rigorously tested under real home barista conditions. PLA, when printed and finished correctly (as we do), offers excellent durability — ideal for espresso prep tools like knock boxes and WDTs.
Can I customise the colour or engraving?
Yes, we offer a range of colour options, and custom engraving is available on select items (like knock boxes or wdt tools). Just choose your preferences on the product page.
Do your knock boxes fit all espresso machines?
Our knock boxes generally come in two to three sizes — and if your espresso machine has a large portafilter, you may want to consider sizing up.
We recommend checking the product dimensions listed on the page and measuring your space before purchasing to ensure the perfect fit for your coffee station.
Are your knock boxes dishwasher safe?
Our knock boxes are not dishwasher safe. As they are 3D printed using PLA (a plant-based material), exposure to high heat and steam in dishwashers may cause warping or surface damage. We recommend hand-washing with mild soap and room-temperature water, then drying thoroughly.
