All 3D tools

The face and case are individual, printable STLs; they fit with a nominal clearance and are intended to be fixed with tape or adhesive, not snap-fit. Use low-voltage, low-heat LEDs only; never enclose mains wiring. These are independent ToolsVault tools. STL dimensions are millimeters; test fit, slice, and inspect layers before printing. No cloud processing or paid exports.
