SD Memory Card hold

It's a key holder that can hold a SD Memory.
It's made by 3 parts: 2 can match together with some pins and the third component fits perfectly inside the hole thanks to my designed snap-fit.
(but it might be necessary to smooth an angle with a sand-paper)
Soon I'll upload also the New version ;)
ps.: I'm sorry if it looks ugly in my pics, I did fast prints just to make sure the snap-fit works well.
