I'm at work and running out of floppies. Why does this always happen to me?

The only 3.5" disk I at at work had no logo on the shutter so I tried to laser-engrave one, but the inconsistent line thickness on my SVG made it come out kinda terrible. I don't have another disk (of the right size) on hand to try again, so it'll have to wait until tomorrow.

I did the back of my ONE FLOPPY and it turns out doing dense engraving run (instead of score) using filled polygons looks pretty damn good.
