About this 3D model

Missing steps in your motors? Belts loose? Have backlash? Calibrate your printer using this block! The dimensions are 30mm x 20mm x 5mm with a 12.7mm hole in the middle that is 2.5mm deep. This brick will tell you if any of your axis are running funky! Post pictures of your bricks! As you can see I am having problems with my Y-axis right now but that'll soon be remedied
