Grab one of the empty plastic frames (runners) that came with your kit, preferably one of the same color as your piece.

File or clip down a piece of the runner to use as support.

In this guide, we will be clipping the part for support as the piece is too small to fit a filed down support piece.

It is not mandatory to use a runner of the same color, or even one from the same box of your original kit. It is simply recommended for visual appeal.
