C001 Micro SD card holder and case

This is a remix of really nice “Improved SD and microSD Card Cases” by MartinNohr. I find this design almost perfect except for the case that has an ugly hole that doesn't cover 2 memory cards.

I'm going to use this cardholder in my bike trips, this is why I need better protection from dust and pressure. I redesigned the case to make the hole as little as possible and made special nail grips on the cardholder to get it out easier. The stuff that holds the cards in the original version works perfectly for me and I kept it in this version.

Printing instructions and how to use: 

Print time is about 3.5-4 hours… Don't set a fast speed for the cardholder, the accuracy is important here, so 50mm/sec would be OK. The case may be printed faster if you don't need very accurate surfaces.

PS: Cura says that the case is not watertight, this is because I had to deal with the original mesh in Blender - it is not the best way of designing new things, but it's faster than creating a new model in FreeCAD :) Don't worry and print it, everything will be fine! 

Personally I don't care about the license, but the original thing has the Creative Commons - Attribution license, and I set the same so that the users could find the author of the original version, because I only slightly changed it to ensure 100% protection of the micro sd cards and more attractive appearance.
