I have discovered this great "air-curing" rubber that can fix anything. So instead of trashing a power supply, shoes, racks, hooks. Just try Sugru, it looks to me that you can fix almost anything with it and I'm not getting any money or free stuff from this company.
It looks like some play-Doh, it can be formed by hand and once it's exposed to air it cures to a tough flexible silicone rubber overnight.
It looks like the possibilities are endless.
