I also decided to alter the cavern river tiles by @Lifeburn and make them openforge 2.0 compatible @devonjones.Now you should be able to combine this tiles with any openforge bases (2x2) and use them alongside any other openforge 2.0 tiles. I also redesigned the rivertile edges a littlebit so that they fit a littlebit smoother in between the other cavern tiles.
Use these along my other cavern remixes found here on cults :
EDIT: I smoothened the edges of the narrow rivertiles a littlebit, so they better fit together.
You'll find all parts used for my remixes listed on my thingiverse:
