"Nano Sim" to Sim Adapter (Tight Fit for iPhone 3GS)

I made a new Nano Sim to Sim Adapter, because i needed one with a very thight fit. The Nano Sim (T-Mobile, Germany) snaps into palce and stays in place - i even if i drop the adapter. The adapter has also a tight fit in the iPhone 3GS Sim-Draw.
I printed many versions, to make it fit perfectly (for my Nano Sim and iPhone).

A Tip for beginners (like me)
The smal flaps, that hold the Nano Sim in place, are only 0.2 mm thick. Therefore, you have to print the first layer with a max. thickness of 0.2 mm or these Flaps will not be printed (as i had to learn on this project).
