Elegoo Neptune 4 Pro extrude/retract vizualizer

Hello !

If you like my work, please rate it.

The Elegoo Neptune 4 Pro 3D printer extruder has a gear on top that is connected to the extruder. I attached a small pointer to this, which makes the extrusion and retraction clearly visible. This can be easily attached and removed without disassembling or modifying the printer. It has no practical use, but it is definitely spectacular and funny.
The ver02 is different in that the clock is lower and the pointer rotates more slowly due to the smaller gear.

To put it together, you need a 2mm diameter metal rod and a little glue. You can experiment with other materials for the shaft.
