Large calibration square

thingiverse

I tell people in IRC how I calibrate my X and Y steps/mm, and they immediately ask for a .stl - so here it is. A 100 x 100 x 1 mm hollow square, for calibrating your X and Y Axis steps/mm, and for squaring your Y axis. Instructions Print it. Measure It. Use http://calculator.josefprusa.cz/ to determine your correct X and Y steps/mm. Use a try square to determine how far out of square your Y axis is.
