To make myself a copy of the print-and-play (PnP) solitaire boardgame Under Falling Skies I wanted to make the markers more interesting than the originals. I made the aliens based on the original Space Invaders game (but I haven't perfected my own version of those models yet), and made individual 3D icons as markers for the science, damage, and power tracks, and for the location of the excavator. This is the power marker, based on the 2D icon on the cards, but in nice 3D. It is a bit delicate, but it works fine.
Designed in Tinkercad.
Print with supports! Remove supports very carefully to avoid breaking the narrow ‘ankle’.
