Thumbnails
Every file shows its geometry.
Icon, list, column and gallery views render the real mesh, so a folder of exports stops being a wall of identical file icons.
A Graviro utility for macOS
See your 3D models before you open them.
Meshlook brings visual previews of STL, OBJ, and 3MF files to Finder. Browse model thumbnails in your folders, then select any file for a larger Quick Look preview.

A folder of exports — every icon identical.
Your model folder, finally readable.
Meshlook is a Finder extension, not another app to keep open.
Quick Look
Space bar, then a bigger look.
Select a file, press space, and check the part before slicing — without launching a separate 3D app.
Private
Nothing leaves your Mac.
Rendering is local. The developer collects no data: no uploads, no telemetry, no account.
Supported formats
Three formats, done properly.
STL
Binary and ASCII, including multi-solid files from CAD exports.

Before you install.
Does it slow Finder down?
Thumbnails are generated once and cached by macOS. Large files render progressively, so scrolling stays smooth.
Do I need to keep an app running?
No. Meshlook installs a system extension and then stays out of the way. There is no window and no menu bar item.
Does it work on network and cloud volumes?
Yes, including SMB shares, Dropbox and iCloud Drive once a file is downloaded locally.
What happens to my files?
They are read, rendered and never written to or transmitted. Details are in the privacy policy.
