I extended out C3PO's base to accommodate the five "same scale" Buildables.

Here's a summary of the LEGO news article.

The user /u/Let_Them_Fly extended the base of the C-3PO Buildable figure to accommodate five other "same scale" Buildables. This modification allows for a more cohesive display of the figures.

The post doesn't specify the exact set number for the C-3PO Buildable figure, but it does mention that the base was extended to fit other Buildables of a similar scale. This suggests the user wanted to create a unified display, possibly including other iconic characters from the Star Wars universe.

The modification is a creative solution for LEGO enthusiasts who enjoy displaying their sets. It allows for a more visually appealing presentation of multiple figures, enhancing the overall aesthetic of a collection.

If you're looking to display your LEGO figures, consider getting a LEGO display case to showcase your collection.
