Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I haven't watched the video, but they probably only used English language torrent sites and western search engines which censor a lot of piracy related results, I was able to find these in a few seconds using Yandex:

torrents: https://rutracker.org/forum/viewtopic.php?t=6719432 (in Russian but you can easily use built in browser translation to make it readable)

and direct downloads: https://stl3d.pro/category/3d-print-model/warhammer/ (that second site requires signing up for an account)

I was able to get .stl's from both, I don't have a 3D printer to check how they'd come out but they look good in a viewer

I also found some telegram channels but haven't tested those links

Seems like the author isn't super familiar with piracy and didn't put in enough effort and do their due diligence trying to find the files beyond surface level searching, or (tinfoil hat on) are a GW plant trying to discourage people from finding affordable ways to engage in the tabletop side of the hobby

STLexandria torrent on TL?

STLForest on telegram

I'm on a number of telegram groups that shares models, there was a big nuking last year, with them going unlisted, but still active. Russians don't give a fuck
