I take little to no credit whatsoever for this. It's all just remixed faces for the awesome Jack-o-Lantern from thjelmfelt. You'll need his design to make use of any of these faces I slapped together.
I just grabbed a bunch of vector graphics, mostly sci-fi, some automotive, and band logos, and extruded them into holes in TinkerCAD. Some of them may not be ideal for letting light through due to smaller details. I have not yet begun to print them.
***I will continue to add more as ideas arise. Feel free to leave requests in the comments.
7 September, 2018. Added 12 new faces. Some are more generic Halloween art, and a few are hobby specific & requested by friends.
