This model is a simple, lightweight and robust tri quare to measure and draw lines at 90 degrees on materials. It has mm increments and readouts (thanks to comments on previous models).

Throughout the many models I will release, I will keep them simple and easy to print, and I am aiming at creating 3D tools and accessories that don't require any additional parts. So I you would like to support me, please check out my other tools and accessories I have made for you and me.
