3D bases matching the five basic asteroids/debris markers for Star Wars Armada. These are designed to fit a 3mm perspex rod to support the actual asteroid itself (I used lava rocks). Note that the rod hole is a very tight fit (I gently hammered mine in), so shouldn't require glue. I did slice my ones with Detect Thin Walls enabled (as the wall next to the rod hole is very thin).
When printed as is, they are almost identical to the original cardboard ones in the base game. The base height is about 2.8mm, and the widget token holder is 11mm diameter by 5mm high (matching the ship base widgets). I added these to provide additional support for the perspex rod, and give the ability to add numbered tokens to asteroids if a given scenario demands it.
If you mirror them along the x-axis in your slicer tool, and print a second set, you'll have the 12 flavours of asteroid base.
