Currently, there is no option to craft a covered dropping conveyor.

For builds that use the dropping conveyor in combination with covered conveyors, this creates a weird visual style that lacks consistency.

Additionally, the lack of a covered dropping conveyor can make it difficult to navigate around a dense factory that uses dropping conveyors frequently. Personally, I like to use dropping conveyors as a means of filling an inventory A until it is full, and then moving the items into inventory B (which usually circles back to the start of the pipeline).

It would be appreciated if a covered dropping conveyor was implemented 🙂
