Those things are mainly calibration items that you can use to calibrate your 3D Printer.

Updates:

• 2016.01.22 : Add Cad files for Calibration objects
• 2016.01.22: Add retraction calibration object
• 2015.08.10: Add Scalar - RippleCalibration_v2.stl, similar model but the pattern is in both X and Y axis

-Clovert.stl: A small clover shaped part with round and flat sides.
-Scalar - Calibration_High_Frequencies.stl: small part with very high frequency shape, it will help you check that the printer is capable to print high detailed parts.
-Scalar RippeCalibration.stl and Scalar - RippleCalibration_v2.stl: A flat part meant to be print vertically. On one side you will find vertical pattern with some low and high frequency patterns. The other side has different size of round shaped holes. You will be able to see possible ripples due to vibration with this calibration part.
-Scalar - Calibration_Roundness.stl: Made to check the roundness capabilities of the printer. Different size of cylindrical shapes on top of each other shaped as a pyramid.
-Calibration_retraction.stl: is composed of a few towers spaced differently from each other. Print them empty, the goal is to test that the retraction is working great.
