Murphy The Library Cat (with secret book box) -The Complete Package (multi and single material)

3D model description

Murphy the Library Cat is a British shorthair cat. He is smartly attired with a collar and tie, wearing his spectacles (cats have poor close vision so he'd need those to read:-)) and unlike other cats who are content to sit on a single piece of paper, Murphy sits on a book.

This book however, happens to be a secret box: it's lid held in place by magnets. He also wears a pair of spectacles (printed in flexible filament) and wears a shirt collar and tie. Originally, Murphy was not published and was used by me as a gift for friends and family only. However, when I took him to MRRF(Midwest Rerap Festival ), he proved very popular with many requests to make him available to the public, so I decided to do just that. Incidentally, that is where his name comes from: MRRF = Murphy.

Murphy has a choice of a plain shirt collar and standard British style school tie or a fancy collar with a bow tie. Due to the way these are designed, the collars and ties are not interchangeable.

Murphy is available in both single and multi material versions. this way, nobody has to miss out

The largest model in the Murphy assembly is the cat body, the dimensions are:

length: 109mm, width: 138mm, height: 160mm

If your printer can accommodate this then you are good to go!


Murphy is a 3D printed multi part assembly and is available in multi and single extrusion versions (although to be fair, the only parts of him that use multi material extrusion are his head and the pages of the book).

You will be purchasing:

Murphy the Library Cat: The complete package

If you get this package then you will not need to purchase any others. It includes ALL the Murphy files.


If you own a printer that extrudes a single material only then please look at the Single Material package:
