Meshory

Meshory is a local-first 3D print file organizer for Windows, macOS and Linux.

Point it at the folders your STL and 3MF files already live in, whether that is an internal drive, an external one or a NAS. It indexes them where they are: nothing moves, nothing uploads, and there is no account.

Every model gets a real rendered thumbnail and opens in a built-in 3D viewer. STL, 3MF, OBJ, FBX, STEP and 3DM all render. It browses inside ZIP, RAR, 7Z and tar bundles like folders, with no extraction step. Duplicates are matched by content hash and geometry fingerprint rather than by filename, so a renamed copy or a re-export still lines up.

Built and hardened against a real 118,270 model, 3.5 TB NAS library before it shipped.

One-time purchase. No subscription, no cloud, no seat pricing.
