Gaming 15 Corners

I recently bought an Inspiron Gaming 15 laptop.  I mostly like it but there is one big issue...the front corners are super sharp for no reason.  I wouldn't have bought it if I knew this; Best Buy had it on a low table with no chair so when typing my wrists came nowhere close to the sharp edges.  Since I've been using it, my wrists have gotten torn up about every time I touch the keyboard.

Is there some kind of padded skin for this laptop?  If not, is it safe to take a file or some sand paper to the corners to make this thing usable without a USB keyboard?

Thanks.
