Citroen 2CV key chain

I've created this keychain as a gift for a friend. This eye-catching var was her very first vehicle and is gone long ago.

Up to now I had not chance to print this model, but Slic3r seems to be pleased with the STL-file.

The design is intended to switch the color of the filament after printing up to a height of 3mm.
As soon as I'm back at my printer, I'll print the first layers with black PLA and use red PLA for the rest of the keychain.

*Update:* I finally printed to with color change
