Based on my Halloween fan grills, enjoy these spooky drink coasters!

In the photos, I printed the jack-o-lantern face down, and it came out fine visually, but with lots of pores that would undoubtedly let moisture leak through.

The cobweb designs are printed face up, and their bases are much more solid, although they're still perforated a bit due to under-extrusion. Increase your flow rate and print face up if you want to be sure the bottoms won't let liquid seep through.

I did a manual filament change a few layers from the top in all cases to get the nice depth effect.
