25 Geeky Uses for Sugru

Matthew Hughes 21-01-2016

Sugru is awesome. It’s an affordable, pliable, rubbery substance, which you can use to modify or stick together almost anything. Don’t believe me? Here’s 25 geeky uses for the stuff.


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 How to Fix Broken Headphones Despite having a reasonable pair of Sennheisers and looking after them, my headphones broke recently — like they always do. Rather than replace them, I decided to repair my headphones. Here's how. Read More , too.

Glasses Repair

Glasses are expensive. But 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 an added bonus, this will then be molded to the exact shape of your nose bridge, making them more comfortable to wear.

Magnet Stands

Sugru and magnets are a match made in heaven.


Together, they offer 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.

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.

Fix Frayed Cords

Macbook chargers are notorious for being fragile, with the thin sheaf of plastic that protects the metal wires being especially prone to fraying. Personally speaking, I’ve gone through about four of them. 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 Anna Hegedus shows you how to patch tired-looking laptop cords, simply with a bit of Sugru.


Moleskin and Sugru Tablet Case

It’s no secret that I’m a big fan of Moleskin notebooks. 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, as this reddit user found out. Our very own Kannon Yamada has written about how to use Sugru to build a tablet protector How to Ruggedize Your Android Tablet Got a tablet but can't find the right protector for it? Or do you want to ruggedize your tablet on the cheap? Read More , too.

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.

Repair Shoes

Sugru is a flexible, 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.


DIY Oyster Card

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

This pre-paid card allows you to cheaply and easily access London’s bus and tube network, simply by tapping it against an RFID reader. But the cards themselves are easily misplaced. Personally speaking, I’ve lost about five of the buggers.

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.

    The idea of the DIY Oyster Card keychain thing sounds like it would be a good idea for the Vancouver Compass Card, but sadly I think the Compass Card doesn't have one singular chip that can be removed. And the DIY option probably wouldn't suffice when transit police want to check your fare. (Right now they don't have scanners so they're just expecting you to flash your card to show you have one).

    Either way, cool list.

    Can Sugru go through a washing machine/dryer safely and without melting?

        The metal button came off of a pair of jeans and I think Sugru might be appropriate to attach it again (just one metal half to the other) as long as it's okay in the laundry.

          It should work, although it sounds a bit like overkill to me. Personally, I'd just use a little bit of heat-resistant adhesive.

      Keaton, not entirely sure that sugru will be a good use or repairing a button - my sister tried to use it to repair a cracked castor (admittedly, for a rather heavy cabinet) and it didn't hold so well. I guess you can always try it just to see - because it does depend on how you mold it so that the other half of the button doesn't fall off.
