We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

STL Cosplay Scaler StarForge 3D Modeling Software

Resize Cosplay Helmets to Your Head

STL Cosplay Scaler is built for the helmet and armour files sold on Etsy, Cults and Printables as STL (Stereolithography), a format with triangles but no units, so a helmet can open at the wrong size. This free tool scales the 3D Print STL File to real size, a helmet to head circumference, armour to the wearer's height or a figure to a life size statue, then cuts it into the fewest pieces that fit a 200 mm cube. Every piece fits a 220 mm bed and lines up for gluing. StarForge 3D Modeling Software turns 3D printing wearables into measurement, not guesswork.
