It sounds like you are extruding a little too-much. This will push all edges out a fraction. The problem builds up with more perimeters (each pushes the next out a little bit)

Try pulling your extrusion back just a touch, and that will probably fix your problem.

I did a full write-up of this here:

So, the hole is just slightly too small for the correct coins, I tried 5, 10 and 20 cents, simply because they were laying here.

I have set Slic3r to 1 perimeter to make the perimeters smaller. With 2 perimeters it printed much too tight, with 1 perimeter is was aaaaaaalmost fitting.

Any advice on what settings to look for? My X, Y and Z steps are calibrated perfectly, but the prints just seem to get printed too tight.

I am not using Skeinforge.

This was my first print :) thank you

Instructions

This is a pretty basic calibration piece, howsoever it is more powerfull then it seems.
By uncommenting _one_ of the avaliable coins on the bottom of this code you can generate a calibration piece which should have the exact measures (height and diameter) for the Euro piece you have avaliable. There's not much to do, simply uncomment your favorite calibration coin, export the stl (Design -> export STL), slice it, print it, put your coin in the center and calibrate.
For reference: the measures were taken from this [0] German Wikipedia article

BTW these could also be used for rare coing protectors. just gotta figure how to put plastic over them.
