Tower Crane (BYO Tower)

A fun little toy for my kids. It's a tower crane, but you need to bring your own tower. Goes great on the corner of a table or cabinet. I usually tie it down with string or rubber bands, but the rotating base is detachable in case you feel inspired to design a something that attaches to whatever you'd like to mount to.

Freely rotates 360 degrees
Trolley moves over length of boom, holds position at rest
Winch slides forward to allow free spinning, backward to lock in place
Bucket on the back allows to add counterweight

I've posted the SCAD source if you'd like to customize.
