Blackwing Pencil Extender with Eraser Fixed Geometry

thingiverse

The Thing I remixed this from had some bad geometry. I fixed it up in Blender and it works pretty well. There is a weird nub on the bottom tip, so make sure to use supports for the bottom. If the pencil eraser slot doesn't "grab" the extender well, just lightly pinch the metal slot to make it snugger. Pinch _without_ the extender installed. Use the metal eraser holder to secure the eraser into the eraser holder on the extender.
