This is a ruler that I originally made a few years ago that i used to measure things for any future makes that i would design. This is the second of my ruler models, and so far this one is the best of the ones that i have made.

Printer: Ender 3 V3 SE

Notes:
I recommend using a glass bed to increase quality, also, I recommend turning the speed down so that the little details in it have the best quality possible.
