Is there a chance that you would put this on something like LuLu or RPG Trader with an option to print it on demand?
Currently, the TKG online store sells ONI as a physical product. It will be back in stock soon: https://www.tuesdayknightgames.com/collections/mothership-modules/products/oni
We plan to turn this into a PoD product, but unfortunately I can’t give a deadline for when that will happen.
