About
The world’s first standalone desktop application built specifically to solve one of the biggest challenges in wearable 3D printing:
achieving a perfect helmet fit.
Easy to use
Helmet Scaler is not a general-purpose 3D tool—it is a purpose-built solution focused entirely on wearable fit accuracy.
Every feature exists to save time, reduce failed prints, and deliver professional results consistently.
Thank you!
Best of all, Helmet Scaler is completely free, made possible by the amazing supporters of the MysteryMakers Patreon.
Key Features & Capabilities
Masculine and feminine facial presets
Choose between masculine and feminine facial features and proportions as a starting point for accurate fitting.
3D head scan support
Import your own 3D head scan data for maximum realism and precision.
Measurement-based avatar scaling
Adjust your digital avatar using real-world head measurements to match your exact head shape.
Preset system for fast workflows
Save and load presets to eliminate repeated measuring and speed up your process.
Multiple user presets
Store presets for multiple people—ideal for studios, teams, or repeated client work.
Advanced helmet transformation tools
Move, rotate, and scale helmets—uniformly or non-uniformly—to achieve an exact fit on your avatar, head scan, or preset.
Non-destructive export workflow
The exported helmet is an instance of your original model. No resolution is changed or reduced—only transformation data is applied. Your original file remains untouched, while the adjusted version is saved separately
Strip cutout test prints
Generate strip cutouts of critical helmet areas to test fit without wasting material or time—ensuring the final full print fits perfectly.
Completely offline, private, and secure
Helmet Scaler works entirely offline. It does not connect to the internet, does not collect any data, and does not upload or track anything.
