Slide Paper Binder – Staple-Free Clip (3 Sizes)

I still like writing my notes on paper, and I recycle printed sheets that are half-empty. I designed a binder that you can use either to use blank sheets of paper like a notebook or to keep your printed notes together. I had used a different model before, but it required too much paper, so I designed a smaller one. I also designed it in different sizes. 

PLA is good and strong enough. You don't need to use PETG.
