E3D Revo Nozzle Measurement Jig

This provides a stable reference surface for measuring lengths of Revo nozzles.

3.5mm fits my Mitutoyo 500-181-30 while the 3mm version fits my no-name calipers. If yours is different, the f3d file is provided.

Instructions

1. Print part
2. Glue M4 nut into recessed space

By using this jig, you can establish the Z offsets of different nozzles or possibly find a pair of matching nozzles from your stash.

1. Clean all nozzles with a brass brush while hot
2. Select a reference nozzle (e.g 0.4mm)
3. Measure other nozzles and note difference (e.g. 0.8mm nozzle = -0.09mm difference)
4. Optional: Use difference from step 3 for the starting point of Z-leveling
5. Put difference into Printer Settings → General → Z offset
