How to enlarge negative space (cut-out)?

[mark]

I created letter bodies by extruding text.  Then I did a combine/cut through another target body.  I 3d printed the letters and now I want to print the target body so I can slide the letters into the target cut-outs.  I need the cutouts in the target body to be larger than the letters so the letters fit.  How can I enlarge them?

I tried scaling each letter before cutting but I didn't know how to center the scaling so the letters stay aligned.  What I need is for the interior walls in the target to move out while keeping their position.  I guess I could manually move each letter by eyeballing them after scaling but I was hoping there was some automatic way.

Some help for a newbie?

In the modify menu, pick press pull or hit Q select a faces then put in how much you wont removed, I am doing a screencast now I will post when it's done.

Thanks.  That worked.  It was a pain to select all the faces on a curved letter but they all grew the way I wanted.

If you wont to make it easier to update, if it's not correct you would have to edit it and mistakes are easy to make and if it's in a model with a big timeline finding can be a pita.

A easier way to do it is set up a user paramater then you just change that and it will update.
