The author remixed this model.
I discovered that not all toilet rolls have the same diameter cardboard tube. (What an education it was to print the original model!). My variant has a narrower tube holder part which is also orientated to print upright.
The other main difference is that I have added built in supports for the face. These are simply snapped off the model once printed. There is actually a gap of 0.2mm between the main body - face that is - and the supports.
Final difference is in the orientation of the stomach piece - I used supports to print it but in this orientation, less support material is needed. (Not totally sure whether it actually needs supports in this orientation but I used them anyway).
The legs are the same as those published by koobj.
