It was printed as a non-profit project and I was lucky to be able to get a copy. In case you haven’t heard about HPMOR, do check it out here, it’s amazing.
P. S. I wish I could post a picture of Ukrainian translation of the main Harry Potter series - the covers were absolutely stunning, but those books were left in a different town :(
Found an EPUB here, looks interesting!
