While I was looking for solenoids in my favourite "bargain bin", I stumbled across these cheap wormgeared spindle drive motors and wondered if they´d be good for anything in RepRap world?
Maybe for a huge paste extruder or filament-extruder like
filastruder?

They also have similar motor with a square 4x4mm steel drive instead of the spindle.
