A mash up of http://www.thingiverse.com/thing:5687 paper and pencil holder and http://www.thingiverse.com/thing:5935 Hello Kitty.
New: Posted the HK 3mm file (also available at the link above) and got rid of the parts list that I think was causing confusion. Also uploaded a scaled version.
Warning, I like to use high levels of detail which unless you have a fast machine may take a while to slice. If that's the case, modify the $fa and $fs and/ the scale variables.
Make sure your firmware can go at least 115mm. Otherwise, scale the model to fit. I made the mistake of assuming the configuration was set for a Mendel's envelope and the Z quit at 70mm :/ So from about the middle of the bow up, I had to manually raise the Z. After 3 hours I wasn't going to waste the part :D
