This is scale model of the Minecraft Creeper

Under the covers it's a relatively minor rework of the creeper found here:http://www.thingiverse.com/thing:8346

Changes are: 
- Increased the depth of the toes, making their size a parameter 
- Deepened the holes for the face, made the depth a parameter 
- Parameterised the creation of the connecting holes for the legs. It's possible to print the body & legs as a single piece. 
- Flipped the Z axis, so that it's up the right way in the scad file 
- Cleaned the scad file a bit for readability, reused code for legs/toes.

There are two and a half sets of STL files.  
 - One with 'pins', which can be printed separately, then clipped together and allow the model to be moved.  
 - For a bit of variety there is a minor variant of this where the legs connect to the body with a glue-in 'pin-plate'.  I found this useful sometimes as printing a vertical pin on top of the legs is often problematic, whilst printing the pin plate on its side is quite easy.  
 - The non-pin STLs need to be glued together.

The Steve in the photo is my 'Minecraft Steve' model if you are interested.
