/**
A simple way to drive someng using a electric drill/screwdriver.
Attach a bolt, and add rubber grip (I used an old bike tyre).

My first use for this wa to turn a filament spool, as I wanted to transfer
filament from an nice environmentally friendly cardboard spool to an
(evil if used only once) plastic spool.
