I have to admit, I was so excited to see some sci-fi elements compatible with the Meepleverse that I went and remixed one of Dutchmogul's old terrain sets that seemed perfect for use with Meepleverse. Changes are minimal-- I separated each element from the single file they were in, then resized them a little, added feet to the doors, added a reverse-side terrain texture to the hexagon floors (and divided them into 1x, 3x and 9x sizes) then reoriented them so they print on edge, vertically.
The little meeple-person in purple is Baphira from Dutchmogul's Twelve Days of Meepmas (https://www.thingiverse.com/thing:4043170)
If this is your first exposure to the Meepleverse, check out the original Kickstarter for the full core set: https://www.kickstarter.com/projects/292543184/meepleverse
I also have a lot of meeple heroes and other neat things in my collection entitled "Meeples." https://www.thingiverse.com/Ellie_Valkyrie/collections/meeples
These pieces all print without supports, and presumably without a raft as well, though I always print everything on a raft myself.
