This is the second mechanical pencil eraser adapter

This is the same as my first adapter, but it's a bit thicker. I use this to lift what was left of the pencil eraser. This was done because it's a small part and I wanted to learn to use FreeCad. This works because it is such a small part, but it still took me a bit to get them done since I have never used freeCad. I finally figure out how to use the mouse with it so I thought I give it another try. This is for the black Bic soft Sider Pencil you see in the picture. I don't know if it's even made any more but it's what I have sitting here.
