gadget

/ɡædʒɪt/noun

A small tool or device, often clever or unusual, especially one whose exact name you can't remember.

Example sentence

“My kitchen drawer is full of gadgets I've only used once.”

Affectionately informal, and usually small and electronic these days. 'Gizmo' and 'gadget' both fill the gap when the real name escapes you.
