A5 Binder (6 ring) Hardened Back Panel

I use a 6 ring binder for my work notes and have recently upgraded to a nice soft leather version. The downside is that it's a soft cover and doesn't offer any writing support when it's not laying flat on a hard surface.

To solve this I designed up a quick hard sheet for the back of the binder (200mm, 148mm, 2mm) and ran it out on my MK2S

Printed with PLA at 20% infill and .30 resolution with four tops and bottoms. Works great, makes it much easier to write on off surfaces. I liked how it was more malleable without the sheet but I need to write more so....

Like my design, how about a cup of coffee?
