This is a coin with a cut out of the UK based on one by 'superdan' where he used Australia (http://www.thingiverse.com/thing:250991)

If you want you can use 123D to open the included file and add you own modifications or name to it. (A 0.5mm extrusion into the top of the coin around the UK cutout would look good for text.)

I have also made a similar coin to this with a USA cutout (http://www.thingiverse.com/thing:1532028)

CTC

No

No

0.1mm (or any other resolution)

(Doesnt matter)

Infill should not matter as it is only 1.5mm high so there would be no infill anyway. Print at a fine layer height with a well tuned printer so the fine parts of the cut out come out nicely.

I don't recommend using a raft as it may break away the fine details. Try printing on glue stick or hairspray on a heated bed for PLA or kapton tape with a heated bed for ABS.
