A pencil grip for your 3d Printer! Make sure to resize to the width of your pencil. Additionally, rubbery materials can be used for best possible quality prints, but ABS or other non-ridged plastics work well. If you don't have any modeling software, I recommend using SketchUp and Blender to re-size and edit .stl's and other files.

I printed it out of ABS, but I'd try using rubber as well.
