Posting STL files for member use is fine and all but my browser does not “display” the end product so I can’t see what you are offering.  Therefore I suggest that including a photo (jpeg, png, etc) be a requirement when posting STL files.

But that’s just me…

It’s definitely doable maybe photos of the end product might help.

If you have the software for printing and cutting the images sometimes provides a preview.

I was in a hurry and just making sure the new file extensions would load.
