Big X Calibrator (160x160)

thingiverse

I wanted to make a simple and quick calibration and really liked Michael's from Teaching Tech's X. So I made my own. This one should be 160x160x.5mm. If you need to resize it, turn off uniform scaling to maintain the half millimeter thickness on the z axis. It is meant to be used to live level your bed starting with the skirt. Aside from getting my bed nicely dialed in, I am finding the calibration x's are kind of endlessly useful. From as simple as indoor boomerangs to intertwined multicolor hoops to led strip filters in v-rails and I keep discovering more. 3/6/20 Added a version with a 3x3mm hole in the center to make it easy to put on the wall, stack a few with a thumbtack and give them a spin or arrange them artfully for a starburst effect.
