USB SDCard Organizer

YAHU  - Yet Another Holder for USB

I found an already pretty nice usb organizer (as linked) but a for many others there aren't any usb-c ports. 

There will be a second version in the future with a few improvements (the USB-C is pretty tight at the moment)
Additionally to the print and model file, I added the blend file in order to make it as easy as possible for everyone to make changes on their own.

I added USB C ports and added rounded edges to the openings
