Everyone has a dark and a light side,  why should droids be different? So I present the unholy union of the light sides happiest droid, and the most evil cyborg race ever to wage war against the time line. 

Top spins just like the two precursor robots it is based off of, and of course a lighsaber beats an egg beater any day of the week.

Fit is snug on the spin pin, so a light sanding may help on the top locking wedge edge.
