Build plate leveler

thingiverse

To ensure accuracy in 3D printer calibration, pay attention to the first layer placement of larger, complex parts. A calibration print helps maintain correct print head height above the build plate, regardless of position on the XY plane. Practice with a level build plate is key, as it improves over time. Use a low temperature when printing this part for better results on miscalibrated surfaces. Visit http://www.woodsmokeworkshop.com/wordpress/?p=209 for more discussion.
