Cricut Edding Adapter (example edding 780, 751)

I needed to fit an edding permanent marker into our Cricut and because I didn't found an adapter I decided to create a own one.
This should fit to the smaller eddings, tested with the edding 780 and 751 yet.
The problem with these Eddings is, that you cannot use the edge down there to hold it in place. So I remixed https://www.thingiverse.com/thing:3090732 and created a small edge inside, which then clicks into the space between the metal and plastic part.
You maybe need to bend it a bit to get it down again, but worked fine for me. Just don't want to make it more loose, so it's not wiggling around.
