Earth Versus the Flying Saucers by Zarlor Remix
I just recreated the files as high res to print a little smoother (although on my printer it didn't improve it much) and added a ground piece with a ring inset to add a "force field" which is just a plastic jar about 3" in diameter and about 1" high. A shallow inset in the center of the ground piece holds the bottom of the cylinder to keep the saucer in place without gluing and makes it easy to remove to convert to hanging and swapping out the cylinder for the ray gun. I added a a cylinder insert piece for the top of the cylinder to help center it to the bottom. I separated it from the cylinder to print in black to give the illusion of an opening in the main saucer (hope that makes sense) . I was going to try to 3d print the aliens but they were too small so I printed them out on card stock, cut them out and placed them on the ground piece as shown. I made a few more scaled down saucers to hang in my display case where you can see my Purple People Eater - https://www.thingiverse.com/thing:3003926
Great addition to my Spaceship/Robot collection. Thanks Zarlor!
