Elegoo Neptune 4 Pro filament extrude visualizer

Hi !

This is a simple little gadget for Elegoo Neptune 4 Pro. You don't need to change anything on the 3D printer. It is connected to the gear on the top of the extruder. The extrusion and retraction of the filament becomes visible. The pictures show how to hang it. To put it together, you need a 2mm diameter metal rod and a little glue. Can be colored afterwards as desired.
ver01 is a higher model. The filament should come from above. The pointer also rotates more slowly.
ver02 is a more space-saving version. The filament coming from the side also fits better. The pointer moves faster.

For support, a wooden support worked better for me.
