Bock Converter Box Ventilated

Saw the awesome buck converter box by @Grrenbull here on Thingiverse. Though a buck converter is going to put out a bit of heat due to it's design, so I thought I'd put some vents into it. This is the exact same design, in fact- I even used Tinkercad to just put some holes in it. I could have remade it through Fusion360, but I'm lazy and Tinkercad worked fine. Would suggest printing in a heat resistant filament (PETG, or whatever) but it shouldn't get too hot. I never printed his original file, so the ventilation might not be needed at all... I was just bored and wanted to try to improve something.
