Mini Calibration pieces! For checking how level your build plate is

thingiverse

Managing a school's 3D printer has led to recent issues with leveling the build plate due to worn rubber pads. A temporary fix can be found here (http://www.thingiverse.com/thing:43050), but calibration remains crucial. To make this process easier, I designed mini calibration pieces in various shapes like circles, hearts, and letters C, which take 3-4 minutes to print and weigh less than a gram. For additional assurance, there's also a file with five calibration pieces requiring 15 minutes and 2 grams of filament. Slice up the files and use 0.2 mm layer height and 2% infill for printing. Removing the printed pieces might need needle nose pliers or a razor.
