Notebook psu holder for better thermal longer life time

a classic problem is those high performe notebook chargers / power supplies run ultra warm when the computer is loaded, running electronics very warm eats fast on life time, actually every 10 degree you can make things colder gives you DOUBLE its life time in average.
this holder lift the power supply and let it radiate its heat MUCH better from all sides at the same time, in real life we have now over double its life time, wow..
The power supply we have here is 26.3 thick, so we make the inder measurement 26.5 mm, there are tiny push put markers to grip and bend it out
when the power supply is easy pressed in, it works perfectly that way.
if your power supply is thicker or thinner, simply use your slicer to scale this part.
