If you are looking to DIY anything (seriously, anything) Sugru might just become your new best friend.
Sugru is as easy to use as play-dough, and can be shaped into anything you want it to be. It can bond to almost any material, and keep things bonded when cured overnight. After curing it becomes a flexible sillicon rubber and it will hold even under extreme weather conditions.
If you’re up for a good read, Sugru’s history is recommended. Sugru did not exactly became a success overnight. There are some intense episodes including setting up a laboratory, pitching to hundreds of investors, and ultimately having their first real batch sold out in 6 hours. Success!
Then continue onto the Sugru community, with thousands of examples in which Sugru can fix or make things more comfortable. It’s pretty incredible to see the ideas people come up with!
My personal favourite of course is the USB flash drive my friend fixed with Sugru. Now it’s standing on it’s own two feet again and is back in full use!
