For kids: custom drawings on balls for $200 - Eggbot

I just finished disassembling an Eggbot that I used to make a Poké Ball out of a plain cue ball and it worked great. I have a lot of spare 3D printing parts so the machine cost me nothing but it's only $200 if you have no parts. Also, it is even simpler to make than you might think (incredibly, incredibly simple).

*IF* it is deemed as being acceptable as a Poké Ball by the keeper, I will take a picture and post it (but it is as you think excluding crevices)...

This was the youtube video that made me interested a couple of months ago....

Anyways, again it's wicked simple to build and I think for kids this has a certain attraction.

Here's what a Poké Ball looks like...

NOTE: On tool/pen change calibration for colours I wound up using tracing paper (Bienfang is a great brand) but you could use regular tissue paper. The reason I feel it should be used is because when you change over colours, the pen might shift and/or bleed-out on calibration (calibration = wiggling the pen in).

A drag knife armature, except for small round objects using Sharpie pens instead of blades.

NOTE: I used the Arudino UNO firmware here if you don't want to buy the full kit...

That page is a variant of the official Eggbot. It has a listing of the hardware for its particular case, which looks like it *might* work for pool balls. I'm just not sure about the weight for those 5v motors. If they do work, that specific project would cost about $80 to make the whole thing if you didn't have a 3D printer and were willing to make the frame out of wood or polycarb (which is easy).

Of other interests for the machine using pancake stepper motors could be etching. Apparently people use an extremely similar design to etch with diamond tip bits, but I don't see a open source project for that yet.
 
I’m picturing a65-year-old subscriber to this website. Their first language is not English. They are putting the initial post into Google translator. What would Google translator and pump out?

My first language is English and I have absolutely no idea what an Eggbot is or a pokey ball. I have heard of the hokey pokey.
