- For
- People preparing STL or GLB models for 3D printing
- Worth noticing
- Wide-hole patching and separating touching surfaces are off by default because they can alter intentional geometry.
Field notes
Repair steps are individually configurable, and the interface lets users compare changes before downloading. The page warns that closing wide openings or separating surfaces that touch may alter intended geometry, so those operations start disabled. Downloads are available as STL or 3MF, separately or together in a ZIP; color and texture are not retained. The maker reports that a 300,000-triangle figure takes about a second, and provides an iframe embed with theme and height controls.
