Peugeot 206cc 2005 Key unlock button

The unlock button on my 2005 Peugeot 206cc key fell out. Fortunately I remembered seeing one on TV. Unfortunately, my button is 11mm in diameter, whereas the one I found is much smaller. So I grabbed his, remodelled it, and this is the result

To get the two-tone effect, I inserted an @pause (Repetier firmware on my printer, other firmwares will have some other way to pause and change filament mid-print) into the G-code file at about Z = 3.8mm, printed the bottom in green and top in black.
