I lacked this component in my set, so I crafted one using a board and found its DXF file for laser cutting. The design incorporates a bridge to direct airflow towards the hobbed gear while allowing space for the bolt head. Additionally, it features a larger hole radius for enhanced airflow when utilizing a fan for cooling purposes. However, I noted that the gap for the bolthead is slightly narrow, hence marking it as in-progress.
