USB step converter case

Boost MeIf you like this design feel free to boost it so many other people can see it.This is my design of a simple friction fit case for a dcdc usb step up down converter from amazon. To extend the button through the case, you just need a small piece of filament wich you melt with a lighter on one end and flatten it on the table. Then you insert it from inside of the case. After that you shorten it and flatten it again with a lighter on the other side. (take a look at the pictures)
