FAQs
Everything you need to know before choosing your knock box.
What materials are your coffee tools made from?
All our knock boxes are made using PLA, a plant-based material chosen for its strength, smooth finish, and vibrant colour options.
Are 3D printed tools durable enough for daily use?
Yes. Our tools are designed for daily home espresso use. To keep them in the best condition, avoid high heat, dishwashers, and prolonged soaking.
Can I customise the colour or engraving?
Yes. Many products are available in a range of colours, and custom engraving is available on selected items. For custom engraving, please leave us a message.
Do your knock boxes fit all espresso machines?
Our knock boxes come in multiple sizes to suit different setups. If you use a larger portafilter or have limited counter space, check the product dimensions before ordering.
Are your knock boxes dishwasher safe?
No. Our knock boxes are made from PLA, so dishwashers, high heat, and steam may cause warping or surface damage. Hand-wash with mild soap and room-temperature water, then dry thoroughly.
