3.5" Floppy Disk Drive Transit Protector

While reducing the size of my old computer collection, I've looked for the best way to ship them safely. I have some cardboard ones for 5.25" drive, but none for 3.5".
After some research, it seems that if they are not common, they did exist, as presented by Museums Victoria:

So I decided to create a copy of it, even if I'm not sure it's really useful.
I couldn't get the text to print correctly, but I've only added it to be faithful to the original one.
