Tension Gauge for E3D Hemera

thingiverse

Here is the spun text. A visual gauge indicates tension on the E3D Hemera extruder. The needle moves up as the knurled screw adjusts itself. All 3D printed things that fit other objects can have varying dimensions between printers, this design is meant to be a tight fit so be prepared with your files. The fall of the needle relies solely on gravity and might not work properly in bowden setups where the extruder isn't mounted upright. I am currently figuring out how to add a small return spring. A STEP file is included for you to modify as you see fit. If you create one, please share it with me.
