Yubikey 5C Nano holder

Yubikey 5c nano is meant to be plug in and forget, so it has a very low profile and was made to be difficult to remove. 

But.. it can be too small and too hard to remove at times. And if you accidently dropped it, it can be difficult to find as well. 

This holder makes it bigger, added a lanyard hole so you can attach a colorful lanyard to make it more visible and easier to keep in your bags. 

There is two different version of holder top -  I personally likes the big version, as it is easier to hold with your hand. But if you will just yank from the lanyard to remove the dongle, you can also use the normal sized top. 

======= printing ======= 

The holder top can be any rigid material - it does not flex so rigid ones are fine

The holder has very thin part ( 0.5mm thick ) - be sure to use slightly flexible material like petg or abs. PLA will very easily snap when you try to insert the yubikey. 

======== assemble =======

Carefully insert the yubikey 5c nano into the cutout in the holder part.  Flex the flat portion of the holder a little, so you have enough clearance to insert the usb c into the cutout fully. 

With the selected top part lay flat on a table, align the 2 leg of the holder into the 2 groove in the top part. Press it down so the holder fully inserts into the top part. 

You will notice that there is still a gap between the top part and the yubikey. This is intentionally done to allow tolerance and to avoid breaking the holder during assemble.  To make this tight, cut a piece of paper to width of that slot, and fold it between 4~6 times to a size and thickness that can fit into the slot and insert it. Try get a snug fit so that it won't fall out. This will help push the USB C plug into the socket to maintain stable connection.

Attach lanyard of your choice. Your yubikey should be slightly less likely to went missing now.
