This mod changes the length of conveyors and underground pipes depending on their quality, as well as conveyors speed.
You can adjust these parameters in the settings.
This is a remake of a similar mod by notnotmelon (it wasn't working, so I fixed it as best I could).

To see the actual length of a conveyor or pipe during construction, use the blueprint of an already placed block.
Building a quality conveyor is an inconvenient process, I apologize for that.
Also, conveyors of different qualities do not intersect with each other.

P.S. This is one of two mods I made for our co-op playthrough. Therefore, it's not localized, and is available "as is."
