I'm going to upload parts soon... But I'm wondering, I've modeled an aluminum profile that is used for the framing of some RepRap 3D printers. I modeled it based on a profile sold by Misumi but a few other companies have their own. I'm wondering if we could have problems with supplying parts modeled from existing commercial products?
Should I give it a generic name? I was going for the Misumi part number but now I'm unsure.
FYI this is the one I used here: https://github.com/normandc/Lulzbot-TK- ... -500.fcstd
Maybe I'm unnecessarily cautious, there are already a few files in the FreeCAD-library modeled from existing components, and many sharing sites have been doing it as well for a number of years.
BTW last year a user uploaded a large library of hardware parts to Mantis after a discussion on the forum.

Problem is, the parts were not all modeled by him, and he could not specify their license. There are a limited number of FCStd files, most are STEP files. I opened many and saw that they were generated by Autodesk Inventor, not FreeCAD.
Even if he said this:

They were created by users and available on user forums about 10 years ago. most are no longer on the internet or I would quote the source. They were entered in a table from numbers available from standard hardware sources and from the PEM data sheets that are available on the PEM internet site.
I don't know about you, but I don't think we should use these parts... Apart from the FreeCAD files he made.
