[DF2] Converting Models (3DI -> OBJ)

[RastaManGames]

I saw an very old topic about that and someone provided a link to software on "Nova-Outpost", but now that site seems to be dead.
Is there any chance that someone still have that app?
It can help me with mapping for my "Delta Force" themed Doom project.
P.S.: You can see a part of project here, on Streamable (~1 minute long, ~8 mb sized). This is just weapon pack, but I also working on enemy pack and there is gonna be ~53 terrains used as various missions.
