Things which should exist, but don't seem to

A right angle adapter for an IEC power connector. You have lots of those power cords in a box in the basement, but sometimes you need a right angle power cord. Sure, they exist, in both right angle "sideways" and right angle to the back, but how about a universal adapter? Should cost cents to make, sell for a couple of dollars. I could use a few. And right angle USB adapters?
