h2d extruder indicator

Simple and discreet extruder indicator. Similar to A1 printer. How to:- Remove the transparent cover- Press the indicator onto the extruder shaft (do not force it) to a depth of 3 mm- Replace the cover Attention: High temperature resistant filaments such as ASA or ABS must be used. Since the cover is a little smoky, you need to use a very light color like white for the small circle.
