This is a extension pin and clip that allows you to use the existing factory clip and extend the side panels out by approx 15mm.
This does not require you to remove the original factory clips, they push into the original clips and then provide a clip for the panel pin to secure to.
You do need to print out the lower side panel bottom lock from the original models.
This solution does leave the sides open that will impact airflow and allow for dust ingress.4
The author remixed this model.
This is just a pin / clip taken from the model, it clips into the original factory clips.
You will still need the lower side panel bottom lock from the original model.
