Gridfinity USB memory stick storage - Display / Visibility

I was finally pushed to start my gridfinity insanity by losing several memory sticks on job sites and not realising until I had forgotten which job site they may be at! (hence the gaps in the number series :) ) so I designed a usb stick holder that allows me to see all of the labels on my sticks (which admittedly still need to be relabelled) so that I can see if any are missing easily. This holder is designed to hold slightly chunkier drives like my 64GB Kingston sticks in the photo.
