30齒 模數1 內六角齒輪

Had to swap out a worn gear in my 3D printer and this 30-tooth module 1 hex socket dropped right into place—no filing or adapter needed. The stainless steel feels noticeably sturdier than the plastic original, and the internal hex grips without any wobble.

The hex socket fits my axle perfectly—no wobble at all. Used it to replace a stripped gear in my small robot project and it meshed smoothly right out of the box.

The 30-tooth module 1 hex socket meshes cleanly with my other gears, no wobble at all when I spin it by hand. It's a solid little component, exactly the standard config I needed for the build. Just wish it came in a two-pack, but that's on me for ordering single.
