3D Printer Extruder Indicator
thingiverse
Printed this indicator to for on the extruder gear of my printer. I like seeing that my extruder is moving properly. I have used a permanent marker to mark the squares black for easy identification. I am attaching 2 STL files. A 12mm adapter and a 9mm adapter for the smooth shaft. - The extruder will fit directly with the teeth of the 12mm drive gear. - I also included an indicator that will fit on the 9 mm smooth shaft if you require the drive gear to be flipped over. I left enough space if the grub screw to protrude. A small but important item of my printer. Enjoy.
