Mask Adjuster

Here’s a mask strap adjuster designed for long-term comfort while wearing surgical masks — especially during long shifts.

I modeled it in SolidWorks 2018 and uploaded all the files:

STL for quick 3D printing

STEP for easy customization

Plain text version for reference

It only takes a few minutes and a few grams of filament to print.
Feel free to tweak, improve, or remix it as you like!

Hope you find it useful — and comfy! 😷🛠️
