Technical Details
The pins can be removed, but each pin has been fitted to a specific side and will only work in the side it has been fitted to the correct way up. If both pins have fallen out and you are not sure what side they come from, test them gently. If a pin feels as though there is resistance as it goes in, don’t force the pin down as this can cause the pin to get damaged or stuck.
Machining Method: CNC Turning and Wire EDM

Important!
Each pin has been fitted to a specific side and will only work in that side, the correct way up. Attempts to put the pins in upside down or in the incorrect slot can cause damage to the Cube.
If both pins have fallen out and you are not sure what side they come from, test them gently. If a pin feels as though there is resistance as it goes in, don’t force the pin down as this can cause the pin to get damaged or stuck.

The Most Over Engineered Desk Toy You Can Own!
Made for designers, engineers, thinkers, and anyone who wants to just take a moment and focus, relieve stress, or simply just play around.
Simply invert the cube and let gravity get to work. The tolerances we've machined the cube to are so fine that we had to design a special base to allow the air to escape at a controlled rate. It’s an oddly satisfying cube that works in the palm of your hand.
From Jet Planes to the Palm of Your Hand
We love pushing the boundaries with machining techniques. The process we've used to create this is called wire EDM (electrical discharge machining) and it's now so advanced that in some industries cuts are being made to 0.02mm, with tolerances being held to +/- 0.001mm!
To put that into perspective, the average width of a human hair is only 0.08mm! That's how we achieve such a seamless and mesmerising effect.
Inside the Cube
The Cube is made from solid stainless steel and weighs in at a reassuring 500 grams. It's super satisfying to hold, fiddle with or even just stare at. Each side has been ground completely flat, so the surface is super smooth to touch.
The MetMo Cube is designed to work on any surface, whether it be your wooden desk at work, your living room carpet or even in the palm of your hand.
Finer Wire
The new batches of MK4 Cubes have been manufactured using brand new machinery on a much slower setting, using a finer wire to achieve an even cleaner cut and improved tolerances.
Upgraded Steel Quality
Previously we used 304 stainless, but now the Cubes are made from 316 stainless for a more pristine finish and improved elemental resistance.
Improved Pneumatics
The most satisfying thing about the MK4 Cube is the improvement to the rise and drop. The pins now fall slower and have even better tactile feel and pressure.
MK4 Base
A reinforced anodised aluminium base bolted firmly into place creates a hermetic seal for maximum satisfaction, and the MK4 introduces an enhanced air transfer cavity to improve pneumatic performance.
With higher impact resistance and a chamfered edge, this is the latest in cubic improvements.
So, What's the Deal, Why Does it Cost £249.99?
The level of engineering that goes into creating something this precise is very specialist.
It takes a great deal of skill, time, and extremely expensive machinery to create the MetMo Cube. You might have seen some YouTube videos of similar objects, but they're only very costly demos. This is the world's first metal motion cube you can ACTUALLY OWN!
Want to Gift Metal Motion?
It's perfect for any office, studio, or workshop and really is one of a kind. Each MetMo Cube is expertly finished and comes with a unique personalised authenticity card with its very own serial number.
We love watching peoples' reactions to the Cube, they're instantly mesmerised by the flowing metal and find themselves playing with it over and over again - you can't resist!
View From Above
Each Cube is ground to within +/- 0.1 mm. We didn't really need to do this... but we can, so we did!
With this image we've tried to choose a lighting angle to show where the EDM cuts have been made. In normal lighting conditions they are a lot more subtle, we just don't want to mislead anyone into thinking they're invisible. As far as we're aware this is the closest you can get with this technology.
So, What Actually is EDM?
No, not the dance music. Electrical Discharge Machining is a method of shaping metal to extreme tolerances and uses an extremely thin wire to cut through solid metals. If you'd like an in depth rundown of the process and fancy learning how it works, we'd recommend checking out some YouTube videos for wire EDM.
Why is EDM So Special?
EDM allows us to make very, very precise shapes, structures, and parts to perform very specific tasks where extreme tolerances are required. The interaction of the parts in our Cube cannot be replicated using laser cutting, casting, or CNC machining.
MetMo Cube gives you access and ownership to a very special form of engineering technology, usually reserved for high-budget engineering programs and cutting-edge research.
Why Isn't Everything Made Like This?
EDM remains a niche manufacturing method and is also very expensive. As such, most EDM made products are for specialist purposes, such as space exploration and aviation engineering. There are also limitations to what EDM can achieve and the reduced cost and flexibility of other metal cutting methods, such as CNC machining and laser cutting, puts EDM fairly low down the list of preferred manufacturing techniques.
MetMo Temperature Test
We've been asked before about how temperature changes can affect MetMo Cube, so we've been playing around with heating and cooling the Cube and analysing the effects. Because the Cube heats up uniformly, the tolerance change is so minute that it didn't affect how MetMo works. So in short, even if you live in an extreme climate where ambient temperatures can exceed 40C+ MetMo will still perform.
One of the tests we ran involved heating up the outside of the Cube and allowing the core to be a different temperature. Not really a real world test, but we wanted to try and break it. All we actually achieved was a decrease in drop speed.
I received MK4 cube and it great. The quality of the machining, tolerances are incredible.
This thing is fantastic! It's amazing to watch the pins slowly sink into the cube and dissappear! Amazingly tight tolerance!
The cube came as a gift. However, on my first try, I saw that the pins did not drop at the same speed. In fact, after one pin was completely lowered, I had to push a little for the other pin to come out. Later, when I turned the cube upside down, the two pins did not go in at the same time. However, in the advertisement shown, the pins are entered at the same time. I continued to use it several times afterward. I had difficulty removing and reinserting the pins, but I did not apply any force to avoid damage. However, one of the pins was still scratched and had a small dent in the corner. Even though I placed the pins correctly, it still didn't go all the way into the cube. Each time, some of it was left out. When I wrote an e-mail to Metmo about this situation. They told me it looked like they handled the cube carefully, but if the cube was still damaged it wasn't our responsibility and if you wanted to fix it you'd have to pay for it. And this answer quite surprised me. It was an unprofessional answer that I never expected. I don't understand how the steel cube you are so proud of can lose its function in just a few tries. So how can this be my fault? There is no problem with one of the pins of the cube, it fits into place with perfect sharpness. but the other pin always stays out. When you encounter a problem, the answer you get will probably be the same as mine. A completely disappointing purchase.
I love this little cube as other people say the build is amazing, the way the pins disappear is very satisfying. The is a reassuringly amount of weight to something that fits in the palm you your hand. Positive feedback : User buying experience might need a tweak, I bought the cube last year knowing it will not come till April, this is fine I understand the build process, however it would be nice to know progress of other cubes, i.e. there's x cubes to be made before your batch, and each month i could see the que get smaller. Positive Feedback 2: the little plate on the bottom feels a little out of place compared to the rest of the cube, this could be an upgrade opportunity, at POS or separately, machined stainless with serial number, carbon fiber, rose gold etc.Positive Feedback 3: How about some sort of travel pouch or box, everybody at work wanted to see it, I can see mine doing the rounds.Overall highly satisfied, regards Geoff
I love precise machining. This cube is a perfect demo of what modern machining techniques are capable of. It is a small cube that is fun to play with just like a fidget spinner. I keep it on my desk at work and play with it while I wait for code to compile. Everyone that comes by also loves it. (:
This surpassed my expectations. Definitely my favorite desk accessory, and it seems to be the favorite of everyone else at my office. Amazing engineering. The cube is so smooth and seamless, if anything is perfect it's this.
I am hipnotized by the Metmo cube. Any expectations were more than fulfilled when I opened the box.
I'm a teacher and I teach physics. My Metmo cube is right at the front of my desk and I use it to show the students what I mean by 'precision'! It's brilliant!
Wow, quality isnt the word. This is beautiful

Fun and perfectly made!
Amazing cube!
Amazing cube!
Purchased April 14th - left the UK on the 16th - Arrived in Chicago on the 17th, I live 300 miles north of Chicago. Item has been on tour of the U.S. for the last 12 days. Phoenix, Dallas, Kansas City. You have full control of who you use for your shipper - totally unacceptable. Think I would order anything from you guys again??
Hey Gerard, we're really sorry to hear about the delay with your order. Our shipping times are estimations only provided by the courier, and cannot be guaranteed. We've escalated this with the courier, and confirm it has now arrived and is out for delivery to you today! If you have any further issues, please reach out to our customer service team, and they can get this sorted for you. Cheers Team MetMo
The cube collection continues...
I love this. It is utterly absorbing and like nothing else. To watch the graceful inevitable transition of the parts is like watching time treacling in front of you.
Sometimes I just sit and look at it.
The MetMo cube has arrived and functions as described. The cube is to be a 21st birthday present later this month for a grandson that will shortly commence his Masters in Aerospace Engineering at Melbourne University. With a long held desire to travel to Mars maybe this cube will be the most well travelled!
Excellent quality.
Excellent quality.
I feel it doesn't function as advertised. I can maybe push the two cut outs in and out 3-5 times before the air pressure is gone and they slide and into place.
This thing is an amazing work of craftsmanship.
As part of our business we have had many tools designed for injection moulding , and have in house CNC capability . From order to feedback on progress ,to on time shipping , and most importantly the quality of the product was superb. Congrats to the team - highly recommended .
It’s a very well engineered nickack.
Like nothing I've ever seen, or even thought possible. Truly mesmerizing to watch the metal "melt" back to into shape. Something I will treasure and respect always!
Got this for my best man at my wedding as a favor and I am now jealous
