X Y callibration/alignment

thingiverse

When you have a 3D printer and your X-Y positioning isn't perfectly centered, you can use this design to measure your position and adjust it in your slicer. For instance, in Simplify3D, it's called the origin offset. With my new delta printer, I had to set my origin offset using this design because my first prints weren't centered and when I printed large prints, they would frequently go off the print bed. I hope you guys can find a use for this.
