I made some artwork for these three 3D games in my FE: Asteroids, Asteroids Deluxe, & Warlords.
I made 3 snaps & 3 marquees, overlaying an image of 3D glasses over the existing snap & marquee files. I couldn't find a good glasses image that I could clean up nicely, so I whipped up a model of 3D red/blue glasses in Solidworks & used that.
Attached are the images. Rename them & put them into your FE or MAME installation as you wish. I've set up a system much like the one shown in SGT's guide in the MaLa forum to look for these ROM names in my batch file & launch a different MAME version that has the 3D artwork instead of the normal artwork.
You can also download the entire set here (including the SolidWorks 2009 model of the glasses & the Photoshop file of the glasses screen grab if you wish to modify the art):
