These should work well with 15mm or 18mm figures. Of course, they can be scaled to whatever you need. Moonbase: Print 2 hinges and 1 of everything else. Hinge should be glued to each wing. Use 1.75mm filament as a hinge pin. Saucer Print 4 legs and 1 of everything else. This moonbase is my design. Saucer is not my design. I cut it up for 3d printing and provided it here for the Thingiverse community. Credit goes to Bart Vansteenkiste https://grabcad.com/library/flying-saucer-4
