Pencil eraser insert

Whenever I would be using a mechanical pencil a lot in school, the eraser would always get so low that It was unusable and I couldn't get the eraser out to fill up the lead. So I designed this very simple fix to raise up the eraser just enough to be able to increase the amount of time you can use the pencil. I hope this is helpful!

V2: I noticed that the insert made the eraser to high so that it would be falling out sometimes, so I shortened the base and also touched up the stem.
