Great manual of calibration 3d printer. I have printed a thing through 24h, and finaly it occured that it is too small!! Then I realised that my printer was not calibrated... :( Then after digging Internets I found your manual. it is fantastic. My Ender 3 was about 5% not accurate.

One tip for Extruder calibration. You can calibrate it just in the nylon tube, it is about 20cm long and it is enough for calibration (in Your manual there is 12cm long distance for calibration). I didn't push it to the end to the extruder => than you don't need to heat extruder during this calibration.

Thanks for this, works great.

These links explain how to use this cube to determine and set the extrusion multiplier (flow in Cura)

and here

It's become part of my habit to use this print to test the extrusion multiplier for every new filament I want to print with. I don't often end up needing to change it by much (if at all) but I also made a little lid for the box (which I print the same way) and so I end up with a little box and lid of every filament I try. Here's the lid I made (with a picture of some of the boxes that happened to be on my desk when I went to take a picture of them): https://www.thingiverse.com/thing:3007263

Lid for 25mm calibration box

Great for calibration. Thanks!
