Threaded SD card holder

This is a threaded micro SD and SDHC card holder, I got my inspiration from both the SD card holder from n2b8 (http://www.thingiverse.com/thing:1322805) and the micro SD card holder from bgill (http://www.thingiverse.com/thing:1289250) I posted this as a remix to give them both credit as this is not an original model however it I made it from scratch using fusion 360 so the model is mine.
I was looking around for a micro SD card and regular SD card holder to store my camera sd cards (I have two which use different sized cards) But I couldn't find a holder that either had a lid which would keep them together when travelling, or had slots for both types of card rather than one or the other. So I came across the two holders from n2b8 and bgill, which then gave me the idea to combine the two. please note the threads are a little tight and will need wearing in a bit, I did this by just twisting several times then ( or opening and closing it) but do this gradually as I found with PLA it fr
