Tension Gauge for E3D Hemera

Gauge that gives a visual indication of tension on the E3D Hemera extruder. The needle moves up the gauge when the knurled screw is adjusted.

As with all 3D printed things that are designed to fit other things, dimensions may vary between printers, this is designed to be a tight fit, have your files at the ready.

The fall back of the needle is entirely gravity driven so might not be appropriate for bowden setups where the extruder isn't mounted upright. (I am in the process of working out how to include a small return spring)

STEP file included for your tweaking pleasure.

If you make one, please share.
