There were two files on Thingiverse when I downloaded it.
an STL (which is of course universal) and Blank_Mount.x_t which is a Parasolid file. Right now I don’t have anything that reads the Parasolid file. But I’m looking at a conversion tool and have downloaded an evaluation to see how it handles the Parasolid file.
Ideally I want to see if I can pull it into FreeCAD which I’ve been working with quite a bit lately, and I haven’t checked to see if Fusion360 can import the Parasolid file and also allow exporting to something I could use in FreeCAD. I’d work with it in Fusion360 but at least on the machine where I have that installed it is very slooow compared to FreeCAD.
Not a big deal, just more challenging to do anything extensive with the .stl file.
I’ll see if I can convert the file tomorrow.
