All 3D tools

Gear dimensions are nominal, with a 20° pressure angle on spur gears. Printed gears require backlash and clearance checks. Pulley teeth are a generic, non-certified profile; do not assume an exact GT2 belt fit. These are independent ToolsVault tools. STL dimensions are millimeters; test fit, slice, and inspect layers before printing. No cloud processing or paid exports.
