New in the Maker Shed: sugru

New in the Maker Shed: sugru

We sold sugru at Maker Faire San Mateo and due to the overwhelming response, we now have it online in the Maker Shed! For those that don’t know, sugru is an air curable rubber with millions of uses. It molds like Play-Dough, cures within 24 hours, sticks to nearly anything, and is abnormally tough. I used it to fix my aging MagSafe connector then became addicted. Next, I added some to my space pen (it kept sliding out of my pocket) and a guitar pick (for extended Rocksmith sessions). After that, I decided to embed a tiny NdFeB magnet into a blob and stick it to my iPhone cable. Then I took an identical blob / magnet and stuck it to the back of my dresser. Not only does the blob help me identify the correct way to plug in my phone in the dark, it also keeps the charger hidden behind the dresser until I need it. Dual use and spouse friendly! sugru is sold in packs containing 8 – 5 gram packets. It is available in all black, black and white, or multicolor for a more colorful approach.

    fascinating substance. i wondered if it was non-toxic in terms of making occasional contact with food-stuffs. so from wikipedia we learn: “The formulation of sugru contains methyltris(methylethylketoxime)silane, γ-aminopropyltriethoxysilane, and dioctyltin dilaurate… The company claims that Sugru is classified under EU Health and Safety regulations as ‘not dangerous’, but that it may cause an allergic skin reaction” …silanes aren’t too bad according to a biochemist i know… so that’s a probable maybe.

    Supposedly cured silicone caulking is food safe but I think I would avoid leaving sugru exposed to anything you would ingest for long periods of time. Just to be safe ;)

        Changed to spouse? Nope. Still freaking insulting, intent still crystal clear. Thanks for that slap.
