I think a better idea a add page "TOP paid designs" or "TOP free designs"

It will be easier to find popular designs.
And add a funcion, when you upload a items a photo or STL you can’t upload a PDF files. I’am make a big design “study-cam” is a hard costrucion, and better if people’s donlowd a design with instruction or other PDF file which will make moments such as printing an assembly or rising to a higher level.
