Staedtler marsmicro 775 05 eraser insert

I just finished my last eraser riser/insert/support or whatever you want to call this. I'm only doing this so that I could get a feeling for FreeCad a bit more. I didn't want to make a large file since I'm just not familiar with the program, but I'm slowly warming up to it. I finally got this after a few versions. The paper in the picture is what I was using to get the eraser up more. So that's what this insert are for.
