Discworld - Luggage (Mimic) - Multicolor

Remake of the Luggage (mimic) from Discworld

Changes from the original model:

1. Colorized all parts
2. Stronger walls, to allow them to print properly
3. Removed internal thin walls, which were supposed to be removed manually after printing (no need for them)
4. Parts are now printed together (as multicolor printer allows this) - which makes them much more robust and fit better
5. Added tongue (which was missing in the original model)
