FAQs

Which size should I choose?

Small is best for compact coffee corners or 1–2 coffees a day. Medium is our most versatile everyday size. Large is ideal for busier households, larger counters or anyone who prefers emptying their knock box less often.

Is the knock bar made from real wood?

Yes. The knock bar is made from solid real oak wood and finished with food-safe oil. As it is a natural material, each piece may have slight grain and tone variations.

Are layer lines normal?

Yes. Each KNOCDIC® knock box is 3D printed in small batches, so subtle layer lines may be visible. This is a natural part of the process and not a fault.

Is it dishwasher safe?

No. Our knock boxes are not dishwasher safe. To keep the shape, finish and oak knock bar in good condition, we recommend hand washing only.

Is each knock box made to order?

Yes. Each knock box is made in small batches, often to order. This helps us reduce waste while offering more colours and sizes than standard mass-produced accessories.

What should I pair it with?

For a cleaner coffee routine, we recommend pairing your knock box with a WDT tool, dosing funnel, puck screen, coffee brush or portafilter holder. Many tools are available in matching colours.

I love the design of this knock box, it’s a very smart use of 3D printing! My husband was struggling with his puck screen jumping into our old knock box and this design makes it really easy to retrieve.

I also really enjoy the aesthetics and it’s small footprint on the countertop.

Super sturdy, perfect size, exactly as described and a beautiful sparkle when the sun hits it. Perfect for my coffee station. 11/10

I love the design of this and the way it looks but the practicality isn't there

I love the design of this and the way it looks but the practicality isn't there. I find the box too light, and with it having a smaller bottom, it feels wobbly when knocking the puck in. The wooden part also feels like it might stain over time. The design is beautiful but the product isn't quite there yet.

Great knock box, unique, just what I was looking for

Really lovely, elegant knock box. Matte black looks great with the oak bar. Well made and very sturdy. Came with the WDT tool as well, which has made a surprisingly big difference in shot consistency. Had a small issue with duties since I’m in Canada but the company very graciously sorted it immediately. Think these knock-boxes might be a go-to gift for my espresso-minded friends.

I was worried it because it’s 3D printed it would be to light but I was so wrong! It works great and looks fantastic. Thank you!

Beautiful and unique looking knock box. I had looked high and low for one that fits this aesthetic. Only downside is that the grounds need to be at least semi-dry. I had a wetter puck and water seeped onto the counter which was my only issue with it.

It’s lovely! Just the right size for a day of coffees for the two of us

It’s lovely! Just the right size for a day of coffees for the two of us, plastic is solid and feels robust, wooden bar fits well but can be slid out to clean if needed.
Only things that stop it being a 5
- the two tone colour effect in the photos doesn’t show up in real life, it’s so one colour (which is lovely) so I assume that’s just lighting - but it means it’s a bit misleading and wasn’t quite what I expected. Lovely none the less!
- wooden bar doesn’t appear to be treated at all, it immediately absorbs any wetness and marks, so I’m going to need to oil it. This could easily be done at the point of manufacture, but no great hardship to do at home

Hi Jeremy,

Thank you so much for your detailed review. Feedback like this is exactly what helps us improve.

- On the two-tone effect you mentioned, it tends to show up more strongly in our metallic and galaxy series, especially under sunlight, while the matte olive green you chose has a more subtle finish.

- Each knock bar is treated with Danish oil in our studio, but your experience suggests we may need to review our process or consider using a different oil. We really appreciate you highlighting this.

We’re so glad you’re enjoying the size and sturdiness, and we’ll definitely take your notes on board for future improvements. Thank you!

Regards,
The Knocdic Team

This is the third knock box my husband and I have purchased, we loved ours so much we’ve gifted two (so far) to our coffee loving friends. Love the sturdiness, feel and look of this knock box. It’s always a conversation piece when we host. Couldn’t recommend this any higher, honestly love love love it

Great knock box and even better gift. If you are unsure of whether to get the small or medium, go with the medium. The small is almost too small.
