Bic e.3 Pencil eraser adapter

I have these pencils from my way back and they all have the flat eraser. Meaning I used what could be used and since I have now taken them out of of an old box I had, I needed to use a pencil and noticed that the eraser was gone. Or what could be used. So I just made these adapters to go under what's left of the eraser to lift it up and give me a bit more of the eraser. Not a big thing but how annoying is this, you go and pick up the pencil and you realized there is no more eraser that you an use. I got a few other erasers but I thought I use these small parts to learn FreeCad. It took me a while, but I got them made. Make sure to get the right one since they are different sizes. I'm attaching a picture of the pencil so you know what it fits.
