Lego Minifigures Collection Logo

I love lego and have managed to collect many of the Minifigures collectable series. To display them nicely, I have designed a 3d version of the collection number that is on the packets.
The piece is made up of 3 parts, the white base, red outer ring and centre disc with the numbering on. I used a colour change routine to stop the print of the number discs at 2.95mm (it starts printing the numbers at 2.90mm but found this looked cleaner) so I could change the filament from red to white.
