nozzle indicator

thingiverse

I print things regularly and sometimes have trouble remembering which nozzle size my printer uses. When I couldn't find a suitable design online, I created one in about 20 minutes using Fusion. My indicators match the standard markings for E3D V6 nozzles: zero dots signify a 0.25mm nozzle, one dot indicates a 0.3mm nozzle, two dots represent a 0.35mm nozzle, three dots denote a 0.4mm nozzle, four dots signify a 0.6mm nozzle, five dots indicate a 0.8mm nozzle, and six dots represent a 0.5mm nozzle. This design is attached to my 2020 frame as seen in the picture. The moveable indicator simply rests on top of the frame and uses the 2020 track on the top surface to keep it securely in place. It's a simple yet effective solution. However, I do notice that the moveable indicator could potentially be knocked off by accident if my hand or arm comes into contact with it occasionally.
