Each attachment (mug, hat, plate) uses a simple screw-in or clamp-on mechanical mount.
The attachment plugs into a basic socket on the machine frame, not a pin system.
Only the control cable (for heating elements) uses a keyed multi-pin connector.
Pins are specific to each attachment type and are not interchangeable across brands.
So there’s no universal pin layout—just matching VEVOR-style connectors.
