I would love to see a 3D printable dust cover/USB-C plug protector for the modules. Since all the modules are USB-C and have the locking latches, it would be great to use those as additional support to prevent bending of the USB-C port of a module hanging out in your laptop bag or jacket/pants pocket as well as having the cover keep dust/pocket lint/etc out of the USB-C port.
These would also be great for organization as you could color code the dust covers and/or have space to put a label with the function of the module in a larger print so if you have a few of them in an elastic band organizer you can quickly grab the one you need without needing to read the fine print or flip them all around to see the port (or determine 256GB vs 1TB modules).
What you are specifically looking for are little caps that grab the locking lugs… I’m not sure there is enough “grab-a-bility” to make a sleek looking cap without relying on the USB plug itself for support. Of course, that would defeat most of the purpose!
I think what you’re suggesting could be made, but it would only be a step or two away from being one of those aforementioned carrying cases.
I thought that was Mad Max? Could definitely sling the pair of bandoliers under a laptop bag pretty easily. As a bonus these ones have a belt/waist clip for keeping the bottom in place, so now I don’t need suspenders!
