I'm using NifSkope_2_0_2018-02-22-x64 , Tool_case had animation node and scene, so i took can nif and insert BSTriShape from Tool_case without anim nodes. Changed path in .BGSM to new DDS textures and changed pat to textures in NIF too... After that, any interaction with the object in game was lost. Then I increased the radius Bounding Sphere (not helped) and i find differences between can.nif and Tool_case.nif into 0 NiNode: Children none - Tool_case, Children can - itself, so i add children in Tool_case by himself and it's works... Now when i drop down item, it falls halfway through the texture (center point). https://dropmefiles.com/Fm3yk
