Triangle Ruler for A6 Notebook

This is a right angle Triangle Ruler I designed to keep inside of my A6 sized moleskine. This is perfect for an on the go Bullet Journal, and can simply be placed inside the book.

This triangle is designed with right angle sides equaling 130mm and 80mm and a height of 1.4mm.

[update2019] Added two new versions. Added OpenSCAD file which can be used to create a triangle ruler of any size.
