Models are 100mm X, 100mm Y, 25mm Z, uses 8g of filament. 

I made this Flow Calibration Model to test two things: test flow rates at higher print-head speeds, and the changing angles test klippers input shaper calibration at different flow rates… I also found it helps test your part cooling fan.

I was noticing that my slicer settings were limiting print-head speeds on smaller flow calibration models, the longer sides of this model allowed me to maintain well over 100mm/s… which is about where my part cooling limit is. I found that this can be used to test a printers part cooling fan by setting g-code to increase print speed at 10 layer increments on this model. The single layer outer wall is unforgiving with cooling at high speeds… pushing the speed to the point of print failure (blobbing) has shown me my current part cooling is limited to 80mm/s in this ‘single’ layer worst case scenario … looks like part cooling will be my next upgrade project!

How did your printers part cooling fan hold up? Did it beat my Ender5 @ 80mm/s?
