Little simple robot box with removable head and removable/push through heart.
Instructions
I have printed this now.
Changed a few bits and pieces, including splitting the robots head into two bits to aviod overhand issues.
I have made the head a separate STL for some reason no matter what I did it wouldn't print properly when together with the other parts (it started printing about 4 layers up.
The small disc fits snug in the robots body, this is glued to the robots head completing the box.
