Make your own.

Couple pieces of wood.
some plastic from old milk bottles.
some springs and presto ! you have an axis.

a 1/4-20 thread offers one turn for 50 mil so all you need to do is
add a round shaft knob that you can put marks on.

We spoke about this some time ago and the use was for a foot operated
drill press. you moved the part to your location then stepped on the
foot lever.

Use a solenoid to drive the drill and you are halfway to a full CNC
driller !
