SD Card Holder with Springs

This is a SD Card Holder with internal springs that hold the cards in place.

Apparently SD Cards have quite some tolerances in their size. When I printed a block with simple slits, some of my cards were totally loose and others I could only get in the holder with force. Therefore i design a holder that keeps the cards in place with small springs.

I recommend printing it with ABS since it is more elastic at room temperature. However, I also printed it in PLA and is works as well.
