手搖曲柄 - E-Blox®（需搭配發電機零件99）

The hand crank feels sturdy and turns smoothly, and it snaps right onto the generator part without any fiddling. For our circuit projects

Snapped this hand crank onto the generator part and the little light finally lit up. Crank speed controls the brightness, which my kid thinks is hilarious. Just don't lose it, since nothing runs without the generator piece.

My son's circuit kit was useless without the generator, and this crank snapped right in with no wobble. Turning it actually lights up his little fan project, which he thinks is magic. Wish the handle were a touch bigger for adult fingers, but it works perfectly.
