Eraser Ball (3DP) by Samuel Bernier
Intro: Eraser Ball (3DP) by Samuel Bernier
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.

STEP 1: STL Model
You will first need to download this .STL file, and send it to print.
STEP 2: Find a 3D Printer
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.
STEP 3: 3D Print
I used White ABS with normal definition. I suppose that PLA would also work fine.
STEP 4: Clean
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.
STEP 5: What You Need
Once you have the core, get 14 eraser tips. They come in many colors, so you have the choice!
STEP 6: 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.
STEP 7: Insert
Insert the erasers!
STEP 8: Touch Up
If you DID abuse on acetone, you will need to put a little bit of glue for the assembly.
STEP 9: Erase
SURPRISE! The eraser-ball erases!
STEP 10: Play
It also easily becomes a distracting office game.
Have fun!

Cool! By the way not only RepRap printers you need to remove supports, it's FDM printers. RepRap is a Gcode type, and FDM is the type that melts filament layer by layer. :)

This is a cute idea..maybe I'll make something like this using a styrofoam ball...
