More for inspiration than anything else. You'll have to redraw the clip parts can hold whatever you're mounting if it's a different size. I mounted 8mm cedar planks.
Some design tips, if you're redesigning for your specific case:
Don't use acrylic. It's very brittle on that axis, and it will shatter and dump your entire wall on the ground.
Make sure your material can fit in the slots of your wall rails! I had to dremel them down.
Those curvy bits are necessary. When you push your planks (or whatever) into the clips, those curves will sort of uncoil and provide stress relief.
