Finally a carabiner for your polypanels!  Now you can take any of your polypanel designs and clip them on to anything!  Made some polypanel tools and have nowhere to put them? Print a polypanel carabiner and carry them on your belt loop!  Just print the support free carabiner file first, then pause the panel print and drop it right in as it prints the loop, ensuring that your panel and carabiner will never be seperated!  I have included versions for all four basic polypanel shapes (Triangle, Square, Rhombus, and Pentagon).  I saw in the video comments this what what you guys wanted to see, so I made one!  Enjoy!!!
