Works well. The flags used to scratch against the wall. Put the stoppers on the ends of the flag cross-members. Stops the scratching.

Good quality-easy to drill out for larger center hole - firm texture but seal well. Measurement dimensions were accurate.

I build many 3d print projects. This one was for a carbon filter/ fume Extractor. The stoppers easily transitioned input/output tubing to the main unit.
