Basic file utilities
3 extrasEverything runs locally in your browser and STL exports are free. Uploaded-model flexi conversion is a 2.5D relief workflow rather than general 3D solid reconstruction; moving joints require real first-layer and clearance tests. 3MF color separation is limited to already-closed material bodies, not surface paint reconstruction. These are independently developed ToolsVault generators, not STL Buddy products. Generated prints need checking in your slicer, especially thin details and threaded fits. No cloud AI model generation is implied.
