Düsseldorf Puzzle

#### Intent:
I created a small puzzle to engage the citizens of Düsseldorf by challenging them to see how well they know their city.

#### Usage:
There are 2 difficulty levels:
- the 10 piece puzzle to align the Districts (Bezirke)
- the 2.5mm holes can be used to add flags and assign the 50 boroughs (Stadtteile)

#### Maker tips:
To make the borders a different colour, I simply paused the print after the appropriate level using post processing in Cura and switched the filament before continuing.

I made the flags by cutting the ends off of standard toothpicks, printing the flags on paper, cutting them out and using gluestick to fasten them.

Printing on an Ender 3 V3 SE, all pieces took a little over 12 hours to print with 20% infill.
No Supports needed except for the Rhine pieces for the linking pieces.

When printing i found using an exclusive slicing tolerance in Cura helped the pieces fit together.
