Have an Ikea Billy bookcase and was only able to get two of the LEGO Star Wars kits in there before it got cluttered. I wanted to lift the models up a little so that I could get a third one on the shelf, while still keeping them all visible.

There are two risers. The default one should fit the base on most display models like the Tantive IV. The Falcon has a slightly wider base, so it needed a different riser. The LEGO kits were light via the Light My Bricks kits found here: https://www.lightmybricks.com/

The Acclamator lighting kit stick the light hub on the back of the LEGO model's base, as such, the Falcon riser was needed for the light kit enabled Acclamator.

In the attached image the riser holding the Acclamator was scaled up from 100mm to 120mm and the riser holding the Tantive IV was scaled up from 100mm to 150mm.

Both were printed without the use of supports.
