D3 Hero Tenlog Stock Ducts with nut holes

Note: It looks like HICtop posted an updated part, and it looks to be better than mine so check it out at https://www.hic3dprinter.com/pages/model and see for yourself.

Broke the fan shroud on my HicTop D3 Hero while trying out other designs. When I went to put it back, I found it really hard to hold the nut. I downloaded this design from Tenlog's site.

I 3D Builder hacked some hexagonal holes, thickened up the mounting bar and drew in manual supports.

I've only printed with slicer generated supports so far but I suspect these will work!
