I love the shape of these vintage erasers. When I saw a whole bag of them for only 99 cents at Office Depot, I had this idea for a little office toy. 3D printing fanatics, here is my gift to you.

You will first need to download this .STL file, and send it to print.

I used an UP! 3D printer and it worked very well. It took me a while to optimise it, but I'll post that in an other Instructable.

I used White ABS with normal definition. I suppose that PLA would also work fine.

If you used a RepRap 3D printer, you will need to remove the support plastic with tweezers or needle-noze pliers.You might also want to use sandpaper to remove the rough texture.
What You Need

Once you have the core, get 14 eraser tips. They come in many colors, so you have the choice!
Shine

If you want to be fancy and have a shiny surface, you can use a little bit of acetone. Be careful because it actually melts the plastic so use a brush (real hair because synthetic ones will also melt). If you put to much acetone on the little harms, they will shrink and the tolerances will change.
Insert

If you DID abuse on acetone, you will need to put a little bit of glue for the assembly.
Erase

It also easily becomes a distracting office game.
