This is a very simple mod to do what No More Grind - did back in the day. i.e., reduce (or increase) the price of facility upgrades by a given multiplier, by default, to 10%.

All the actual work is done by sarbian's Custom Barn Kit which is a required prerequisite for this mod to do anything at all, as is Module Manager. All this is is a MM configuration file for those who don't feel comfortable writing their own configuration file to get this functionality.

To change the multiplier from 10% to some other value, open up degrind.cfg in the GameData\NoMoreGrindRedux folders and edit the 0.1s in various places to whatever multiplier you would like. Don't change the rest of the file, and which apply to which facility should be reasonably self-evident.

NoMoreGrindRedux is in the public domain.
