II know it has been solved, but I can't resist a challenge, so I had to try.

Imported your file into Verto Studio 3D using the [font=courier new]assimp library[/font] option. Exported an [font=courier new].obj [/font] file, which was unreadable by SH3D.
Changed the wood texture and exported a [font=courier new]dae[/font] file, and it opened in SH3D right away.

It's a huge model – plenty of storage capacity

Here it is
