Ironing Test Square w/ Raised Info 25x25x3

This little square has seen some things. It's the battlefield where I dialed in my flow rate, surface smoothness, and sanity (in that order). 

Designed for quick calibration on the H2D (but can be used on any of the printers), this test square lets you see how different flow rates affect top-layer smoothness and line consistency. Perfect for tuning all of your favorite filaments. 

Print a few of these at different flow rates (0.98, 0.99, 1.00, 1.01 …) and compare the surfaces. Adjust your settings until it's as smooth as my hairline after a week of test prints. 

Use it, tweek it, share your results, and remember: every perfect top layer is one less reason to pull your hair out. 

Change the raised numbers and letters by double clicking directly on them. Then change them in the pop-up box.
