This is a remix. Really, just a tweak/ bugfix.

1. It is resized to be 'normal' size. The original model, sadly, has some issues with unit and so it imports into slicers in visibly wrong size. I resized the model by 2615% (compared with the theoretical 2540%) to get something that fits my macbook pro charger perfectly after print.

2. The second change is actually a recommendation for a SLICING HACK to make support obsolete. Use Cura's "Make Overhang Printable" setting to make the upper surface sloped - it works perfectly.

   I originally planned to remake the stl to handle the overhang, but this was literary no work, so that's better.
