Creality Ender 3 Rail/Frame/Bar Cover

This is a simple strip to set inside the Ender 3 frame to keep it clean.

I printed a fan cover because I heard lots of debris would come from printing. This turned out to be true and I noticed the plastic scraps still got into some other crevices, so I designed a part to set inside the holes to keep the area flush.

I found that after I designed this. Its name wasn't intuitive for me during searches.

How I Designed This

I measured the cavity in my printer and used primitive shapes in TinkerCAD to model a part to fit. After a few iterations, the part sits flush.
