What Is Sugru? 25 Geeky Uses for Sugru



Sugru is awesome. It’s an affordable, pliable, rubbery substance, which you can use to modify or stick together almost anything.

We understand if you don’t believe us right now, but hear us out. Here are 25 geeky ways you can use the stuff.

1. Custom-Fitting Earbuds

Nothing’s worse than having earbuds that don’t snugly fit into your ear canal.

They’re uncomfortable, and you inevitably get a worse sounding listening experience, as noise from the outside world makes its way into your ear canal. Fortunately, with a bit of Sugru, you can make your earbuds match the exact shape and dimensions of your ear canal. Sugru can be used to fix broken headphone cables, too.

2. Glasses Repair

Glasses are expensive. But unfortunately, they’re also really easy to break.

Enter Sugru. With a few dabs of this magic substance, you can easily repair any defects or breakages with your spectacles. For example, if a nose pad falls off (as they so often do), you can simply replace it with Sugru—as explained in this Instructables guide. As an added bonus, this will then be molded to the exact shape of your nose bridge, making them more comfortable to wear.

3. Magnet Stands

Sugru and magnets are a match made in heaven.

Together, they allow you to attach and detach metal objects to whatever you want—without having to use nails or glue. Just check out this video from the makers of Sugru, where they use the stuff to create a DIY bike lamp.


4. DIY Phone Wallet

Tired of having overloaded pockets all the time? Why not turn your phone into a DIY credit card holder and keyring! All you need is a bit of Sugru and this Instructables guide.

5. Fix Frayed Cords

MacBook’s chargers are notorious for being fragile, with the thin sheaf of plastic that protects the metal wires being especially prone to fraying. If you’ve got AppleCare, you’re fine. Just take it to the Apple Store, and they’ll replace it there and then.

But if you’re looking for a cheaper alternative, check out this video. Here, YouTuber Hugh Jeffreys shows you how to patch tired-looking charging cords, simply with a bit of Sugru that cost just $8.

6. Moleskin and Sugru Tablet Case

There are plenty of Moleskin notebook fans out there, and for good reason. They’re just amazing quality, and the paper feels great to write on. Plus, the cases are hardy and strong.

When you’ve finished with your Moleskin notebook, consider turning it into a tablet case. With a bit of Sugru, you can turn it into the perfect Nexus 7 case, you can see for yourself on Imgur.

7. Pen Holder

Never lose a pen ever again! With a bit of Sugru, you can create your own DIY pen holders and attach them to whatever you want. Plus, they’re about a million times less embarrassing than wearing a pen-protector.

8. Repair Shoes

Sugru is a flexible and strong material that’s also fully waterproof. With that in mind, it’s ideally suited to repairing wear-and-tear in shoes. This video shows you everything you need to know.

9. DIY Oyster Card

For Londoners, an Oyster Card is just as essential as a credit card.

This prepaid card allows you to cheaply and easily access London’s public transport network; all you need to do is hold it against an RFID reader. The cards themselves, however, are easily misplaced.

So, why not make your own Oyster Card keychain or something that’s easier to keep track of? With only a few basic implements (Sugru being one of them) and a bit of imagination, you can create your own custom Oyster Card.

Remove the chip and put it in a blob of Sugru with a chain attached, and you’ve got your own Transport For London keychain. Make a Sugru RFID ring, and you can enter London’s underground train network simply by waving your hand like you’re John Anderton in Minority Report.

10. Phone Bumper

So you’re walking down the street with your cellphone pressed to your ear, and you get distracted. You quickly lose your grip, sending your smartphone crashing to the floor. Seconds later, your once pristine phone is scratched and with spider web cracks running across the screen. If this has happened to you, we understand your pain.

Luckily, you can avoid this happening again in the future if you use a phone bumper. These can be bought from Amazon for about ten bucks, but there’s an even cheaper way. Just make one yourself using Sugru! Check out the below video.

11. GoPro Helmet

If you’ve ever wanted to make first-person videos, here’s your chance: Using a GoPro, a blob of Sugru, and a motorcycle helmet, you can build an affordable helmet cam. YouTuber BabyBlueUt explains how.

12. DIY Key Hook

If you’ve ever spent hours looking for your car keys, only for them to be stashed underneath your sofa, you’re going to want to pay attention to this video. Using just a blob of Sugru and a cheap household magnet, you can create your own DIY key hook.

13. Cable Organizer

It can be frustrating dealing with cables when every USB port of your computer is occupied with something: a phone, a keyboard, a mouse, and maybe even an external hard drive. The problem is, this is so incredibly messy.

Thankfully, with a bit of Sugru, you can banish unsightly cable chaos for good.

14. Glass Bottle Stopper

You love wine but hate what it turns into when left exposed to the open air for a few days: vinegary and sour. But with a bit of Sugru, you can create your own bottle stopper and preserve that delicious wine goodness.

And as the below video shows, it’s good for chemical test tubes, too.

15. Pencil Sharpener

Pencil shavings are one of life’s little annoyances. They get everywhere, like glitter, and no amount of vacuuming will vanquish them. YouTube Christina Smith has found a better way. Using an old mason jar, a drill, Sugru, and a pencil sharpener, you can build a sharpener that catches shavings, allowing for easy disposal.

16. 3D Printing Filament

Yes. You can use Sugru as a 3D printing filament. Why not? It’s a sturdy but pliable material, and can quickly set into a chosen shape. Watch and see how HYREL 3D pulled it off.

17. Repair a Roomba

If you hate vacuuming, the odds are pretty high you’ve stumped up the cash for a Roomba-style vacuum. However, some parts, especially the brushes, are prone to breaking. Florian Klien found a simple way to fix this. Watch and see.

18. Tablet Stand

It’s easy to get tired of holding up your tablet in bed which might lead you to want a tablet stand. You could buy one new, or you can re-purpose an old desk lamp into a stand using a bit of Sugru to help you out. You can find a good guide for this project over on the Sugru website.

19. Dash Mount an MP3 Player

Another cool use of Sugru is using it to attach electronics to a car’s dashboard. YouTuber Ian Fagan shows how to attach an old Sandisk Sansa MP3 player using just a small blob of the white stuff. Before you watch the video below, check out the Instructables guide.

20. Fix Your Nokia N900

The Nokia N900 was a beloved model of smartphone which ran Nokia’s doomed Maemo operating system. Unfortunately, it suffered from a defect that caused the GSM chip to disconnect from the mainboard. Fortunately, one Reddit user has found a way to fix this, using Sugru. You can see his process on Imgur.

Bear in mind that it requires you to disassemble your phone, and this almost certainly will void your warranty.

21. Customize Your Games Controllers

If you want to customize your controllers with your own logo or design, you don’t have to make any warranty-voiding changes. All you need is a packet of Sugru and your own stamp, as demonstrated by the below video.

22. Raspberry Pi Laptop

If you’ve ever wanted to use your Raspberry Pi on the move, here’s your chance. Using the Laptop dock of the Motorola Atrix smartphone, some Sugru, and a 3D printed Raspberry Pi case, you can make your Raspberry Pi portable. Adafruit has all the details you will need for this project.

23. Android Desktop Dock

Amazing. With just an NFC tag, a bit of Sugru, and a $1 smartphone stand, you can create your own programmable Android desktop dock that knows when the phone is docked. Just check out this video by YouTuber Parker Harrington.

25. Silence Noisy Household Objects

When hit, Sugru doesn’t make that much noise, making it ideal for soundproofing household objects. In this video, the makers of Sugru show how it can be used to silence anything from a noisy tin pan to a clattering toilet seat.

What Will You Use Sugru For?
