Sugru is the world's first mouldable glue that turns into rubber.
Sugru can be formed and shaped by hand for up to 30 minutes once it has been removed from its packaging.
Sticks to almost anything
Sugru forms a strong bond to metal, ceramics, glass, wood and some plastics like perspex and ABS and rubbers like silicone and butyl rubber.
Air cures at room temperature
Sugru is like modelling clay when you take it from its pack. Once it's exposed to air, it cures to a tough flexible silicone overnight using the moisture in the air.
In this guide, with sugru, we'll tell you how make custom earbuds safely using sugru to create a perfect cast of the inside of your ear!
sugru is perfect for this because -
it moulds to create the perfect fit for your ear
it forms around the inside of your ear reducing background noise
as the shape of the buds are custom, they are also much less likely to fall out, great for exercising!
- A quarter of a minipack of sugru (maybe line up a couple more fixes so you don't waste the rest!)
- Your earbuds
- Tissue/toilet paper
Cut open your mini pack and tear off a quarter of the blob of sugru. Roll it into two sausages, long enough to just overlap when you wrap it around the inner tube of the bud.
Roll the jelly heads back so the inner rubber tube is exposed. Give this inner rubber tube a quick wipe with tissue paper to clean it.
Press and wrap it around the stem. If your sugru is too long, just tear it off.
Roll the jelly head back over the sugru. Remember to do it to the other earbud!
Slowly ease the bud into your ear, whilst applying light pressure. You might want to play music through the headphones at the same time, to hear what positioning works best.
Give the buds a final press to get the best fit, and then carefully pull them out of your ears.
TOP TIP: Don't twist the buds as you insert or remove them, as it might upset the impression of your ear. Be as careful as you can when inserting and removing the buds before the sugru has cured.
Leave the sugru to cure overnight and in the morning you will have your very own custom-fit headphones! Whoopee!
Look, we even made a video tutorial!
