This model has not yet been published but will be this week! Please check back here for updates or follow me on Twitter for my latest announcements!

Murphy the Library Cat is a derivative of my original 3D printed cat model "Shrodinky: British Shorthair in a box":

Instructables Schrodinky docs

Unlike the Schrodinky models, Murphy is not a money box. Instead, he sits on a book which happens to be a secret box: it's lid held in place by magnets. He also wears a pair of spectacles (printed in Flex 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

Fully assembled, he is 250mm tall


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!

MODEL MATERIAL INFORMATION

Murphy can be printed in a variety of materials providing they can be glued together. However, I would strongly recommend that his spectacles are printed a flexible material(there are a variety of these available now). The spectacles are a delicate model and the flexible material makes them durable. They are not glued in and pinch into the fittings on his nose. As a result, they can be removed easily for packing (if you want to send a print to someone) and easily replaced if they are lost. Glued in standard PLA and other materials are more prone to breaking and damage in this instance.

Very little flexible material is used so a sample packet (available from most sellers) should suffice

ADDITIONAL ITEMS

To make Murphy you need a couple of items to complete the model:

  • 4 x magnets(18mm diameter 2mm thickness) you may use smaller but not larger
  • Quick and clear drying glue capable of bonding the material you are printing in.
    (This document assumes you have read and are following the manufacturer's instructions)
  • Elastic bands (very useful for holding things in place whilst glue is drying)

OPTIONAL ITEMS
Should you wish to add whiskers to Murphy you will need to the following

  • Fishing line for his whiskers (12lb fishing line if printing to scale)
  • Scissors
Cats are cool. This is cool. I look forward to the next instructable.
This is super impressive! Thanks for sharing your process!
