Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5881683. “BackToSchool”

fits on a pencil, spins, and you can still use the eraser. remixed to use the eraser.

.2mm layers, no supports needed.

may have to break it free but not much effort to do so.

I also put a drop of dupont non-stick dry film lubricant after breaking it free, makes it spin well. Also it easier to put this on by sliding the pencils in from the top point end. fits a standard Dixon Ticonderoga number 2 pencil.

I hope you enjoy this model.
