I recommend you look at the new version of this its much faster to build and easier to use.
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 easily 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.
