THØNK 2 | The espresso knock box, optimized

Form, function, and a satisfying THØNK.

Introducing the THØNK 2, now optimized, after two years of daily use and hundreds of community makes and feedback for the first generation.

What did we learn from the first THØNK?

• A lot of you scaled it down to fit limited counter space or simply because you didn't need one that big. It held a lot of pucks, like several weeks worth of pucks at a rate of two a day, but we found that by the time it was getting full, the bottom pucks were getting moldy. So THØNK 2 is about 20% smaller all around for that perfect balance between high capacity and a compact footprint on your counter.
• You overwhelmingly chose to print the TPU pad variant over the finicky hot-glue-basin variant. We were concerned that not many makers would want or be able to print TPU, but that turned out not to be a problem. And then several of you requested that it would be even better if the pad could be aligned and retained without the need for glue. So THØNK 2 now features a TPU pad that clicks in snugly without any adhesive and pops out for washing. It simply aligns itself and stays put.

We also kept everything you loved about the first THØNK: it's smooth and easy to clean, the geometry prevents pucks from splitting or grounds from splashing out, the wide base and subtle curvatures make it exceptionally stable, and it looks great on the kitchen counter.

Printing notes:

Knock box:

• PETG or similar higher temp material is recommended. PLA works ok if you let your pucks cool before dropping them in; over two years, my first gen PLA build warped its base.
• Three perimeters and 12-15% gyroid infill are my preference for a nicely weighted, very robust feeling build, but this is a sturdy box and you can make it lighter without any reduction in performance. It also takes well to higher layer heights.

Knock pad:

• Print in TPU, upside down on its flat top surface. I use 95A. The settings here (2 walls, thinner top and bottom layers, gyroid infill) have been optimized for 95A to be able to snap in and out easily and provide good shock absorption. If you have a different hardness material or prefer a stiffer or softer pad, you can tweak infill and walls accordingly, but keep in mind that it will of course slightly affect retention strength and ease of removal.
