Strugging to upload this .FBX Any Advice Welcome

Please find the .FBX here

When I try to upload this custom object, it says Couldn’t be uploaded.

Please Help.

A post was merged into an existing topic: 3D Model upload troubleshooting collection

We are working on the issue, however
the object is extremely tiny (less the 1 millimeter with millions of triangles)

I recommend opening an FBX file is Windows FBX preview app to see what to expect
