Extruder Calibrator

prusaprinters

<p>This was actually designed for the Voron printers but it will probably work for others. I haven't tested it on any others though.</p><p>I wanted a ruler to easily and repetitively mark the filament at 120mm and then measure the actual extruded filament afterwards to calibrate the e-step. So I made this. I know there are others out there, like <a href="https://www.prusaprinters.org/prints/135572-extruder-step-calibration-aid">Heersert</a> but it doesn't have the millimetres markings, only centimeters. Also, I wanted it to be completely flush on both ends so I don't have to remove the filament or the PTFE tube from the extruder to make measurements.</p><p>This can also be used to measure screws as I just found out.&nbsp;</p><p>There's a groove on the side with the measurements as close to it as possible for easier reading. This was designed for 1.75mm filament.&nbsp;</p><p>I recommend printing it on a higher resolution. I chose 0.15mm</p>
