Nosey Puzzle

I like this little puzzle :-)
I found the puzzle to buy at [puzzlemaster](https://www.puzzlemaster.ca/browse/novelty/packing/12977-nosey-puzzle), where it was called "Nosey Puzzle".

The goal is to fit all 9 pieces in the frame. This seems to be easy at first, but most of the time there will be one piece left, that won't fit!

In the original from the user PrintedPuzzles I found, that the width of the small nobs is much less than on the other pieces. I also wanted to print the puzzle smaller, where tolerances will get too low. Also I wanted to print the pieces with different colours, what's not possible, because all are only in one 3mf file, so You would have to print all more than once! So I decided to create my own version :-)

It is around 75mmx75mmx6mm, including the cover with seethrough letters that will snap on the frame (on a well calibrated printer).

It is possible to print all pieces with the same colour, this will be the hardest way to solve. If You use 4 different colours
