E-Step 120mm Calibration Measure Tool
thingiverse
This handy tool will help you measure and cut exactly 120mm of filament for e-step calibration. I kept fumbling measuring with calibers and holding a marker, while stretching the filament straight. Needed three hands. Allow the material to slide into your entrance hole using this as a guide. Then use a razor blade or exacto knife to cut, or don't cut and just use to measure 120mm of filament from wherever your filament entrance starts. Run the calibration and use calipers to measure the remaining 20mm of filament. There are two versions, one that has a thru hole for cutting, and another for measuring.
