Nespresso screw removal tool

While disassembling a Nespresso coffee machine I got stuck at removing the base's screws: [their head is plainly oval](http://i.fixya.net/uploads/images/5145be8.jpg), making it quite difficult to unscrew them.

Some of them are recessed of a few millimiters in my machine, but others of a few centimeters; it was impossible to remove the deeper ones with some pliers as I did for the others; to have the right tool for the job you have to either be a Nespresso repair shop or buy it online for around $10.

So I measured one of the already removed screws and sketched this printable bit, adding an optional handle groove as a Customizer option.
