These are path parts that are remixed off of the Grass Tiles from Earthworm Tim and the DnD Modular Map Maker by Wolf3DP. Tried to make a large variety of paths for various uses. 

If printing with a 0.2 layer height, add pauses:

    -  before layer 15 for filament change between ground and grass

    -  before layer 23 to filament from grass to wall. 

I don't own an AMS so anyone who does is welcome to add that profile.

I have a sneaky suspicion that if printed with blue and green it may be able to function as stream parts as well, but haven't been able to test that.
