I will leave the old version up for whoever wants it. I have hundreds of panels now and clipping in each one was killing my fingers so i made a much simpler design and let me tell you its so much better takes almost no effort to use and still holds 10 Panels and i can remove them way faster.

I made a crapload of Poly Panels for my kids and really for my self but it's like crazy how many I have now and I am Kinda OCD about it.  So i made a way to keep them clean and organized.  This works with any Poly Panel and you can scale it if you changed the scale on your panels.  a side note i made the Inside Clips 105% larger so the snap on and off easy and still lockin good. 

Each one holds 10 Panels If you guys want I can make a 20+ it would just be longer or wider. Leave me a note if you would like to see that.

Side note: Everything I make are done in TinkerCad. I don't know how to use any other tools at the moment. It works perfectly and that's what counts.
