## What is 3D Nozzle MM?

3D Nozzle MM-IN Helper is a focused 3D printing utility for fast nozzle-size conversions and practical print-tuning decisions.

If you need the inch value for a 0.4 mm, 0.6 mm, or 0.8 mm nozzle, the converter gives it to you immediately. When you are choosing slicer settings, the Tune tab helps turn nozzle diameter into better first-pass setup values without digging through menus or old notes.

What you can do
- Convert millimeters to inches and inches to millimeters instantly
- Jump through common nozzle presets from 0.2 mm to 1.2 mm
- Copy or share clean nozzle-size results in one tap
- Get nozzle-aware starting points for layer height, line width, and first-layer setup
- Estimate required volumetric flow and compare it against your hotend limit
- Stay offline with no account, no analytics SDKs, and no tracking

Optional parts shortcuts
- Open a curated list of common nozzle-related parts in your browser
- Keep shopping outside the app instead of inside a storefront flow
