I saw the original and thought why we couldn't make a customizer version. I saw it easy so I did it. Not much more than a dozen code lines... Not as nice as the original but give it a chance!! its cooool! Do your own monster!!! Open it in customizer and see how the magic is done!!! Or otherwise see how I do my odd jobs ;-)

Included a HiRes normal STL printed as in pic (sorry, bowden extruder this time), working good... My nephew loves it...

I did this thing thinking in special kids, trying to give some help to my sister in law at her job to give them a toy that can alleviate their hyperactivity. She told me It actually works, so I'm pleased. Tecnology is the future, but kids and our help to educate them is a priority. I deeply believe that. We make technology for helping us and not vice versa

Recommended print in PLA. Don't ask!!! For you advanced users, be warned by the sanity checks included in the code....

UPDATE (08-SEP-2016): Made a bunch of this things for the kids and added some pics. Sample STL's from the pics also added. Thought that some small models could be used as earrings like the one showing in the front pic besides the euro coin.
