Picture of Life Size Cardboard Cat

I was trying to think of something I could make for my kittens using the new free 123D software, a laser cutter,  and the giant stack of cardboard I had access too.  The natural choice seemed to be another cat!  Though they weren't as excited about their new friend as I was, I hope they eventually take to it and realize it's not just a new playmate, it's also a friend they can claw to shreds without getting in trouble.  

You don't need a laser cutter to make this project - it just makes it a lot faster.  I used the one at TechShop.  It's easy to turn your own 3D model (whether you designed it or found it on 123D as I did), scale it to any size you want, and print out the plans for it.  123D Make even provides directions for how to put it all together.

Step 1: Using 123D Make

First I used the 123D Gallery to choose a model.  Then I opened the model with Make, scaled it up and sliced it! 

If you want to play with the model that I made, check it out here:  http://www.123dapp.com/3dmk-Make/Giant-Cat/656520

You can see in the second image that the tool bar on the left allows you to do all of these things, including change the direction of the slice and change the form somewhat.  

On the right hand side, it shows you what cuts it plans to make based on the size of your model and direction of your slice.  After inputting the size of the cardboard I had on hand, it compiled a tidy little file of all the cuts for me which I then downloaded.  

The third image shows you the order for putting your pieces together in a neat little slideshow, and highlights which piece is coming up next.  Seems unnecessary until you have tons of pieces in front of you that seem to make no sense whatsoever.  It happens.

If you don't want to play with the model here, and just want to make it, I provided the .eps files for you to download here!

Step 2: Assembling the cat

So now you've got a great pile of numbered pieces that smell like a campfire if you lasercut them.  The neat thing about the file that was generated here is that each piece has the number etched onto it to tell you not only what order they go together in, but also how each piece should be oriented - all numbers face the same way!

If you've decided to cut these out by hand, I strongly suggest numbering each of the pieces using this same system.  Until I figured that out, I had a really hard time figuring out the orientation for the smaller pieces.

Then it's just a matter of gluing everything together.  I used Quick-Dry Tacky Glue, and it was amazing!  Super-fast tack and a really nice finished bond.  

I kept the 123D app near me to help walk me through the more confusing parts of construction.  All in all, I think it took me less than 2hrs to glue each of the 170 pieces together, which was considerably less than I had anticipated!

Step 3: Introduce kittens to their new friend

My cats had very different reactions to the new intruder.  Button immediately ran up to sniff out the new stranger, while Coco ran to hide.  Eventually she came out from hiding and approached the mystery cat that neither moved nor smelled like a regular cat with trepidation and a very puffy tail.

Eventually the kittens got down to business and determined their dominance over the new cat.  It wouldn't even fight back!  But even cardboard cats are interested in hunting pigeons, so in the end they found common ground and settled into their new life together.

OK scoochmaroo, I've downloaded the program, but how do I get your files to open? I'm dumb, what opens an eps file? help! I so want to print out the templates and make this bad boy! :)
Just drag and drop the downloaded file onto a clean page of Winword...As simple as that. :)
Wait I'm dumb I can import them to word, any suggestion on how to make these to the size you used?

Oh gosh, I don't know! I used Adobe Illustrator, and I know Corel Draw works, but I don't know about others. Maybe one of the free programs out there like gimp?

I know if you can also download it directly from the 123D Make page to make sure you get the right size, and you can change the printing options to print them out on 8.5"x11" instead of the 24"x36" format I put them in.

I hope that helps!
That does help thanks a million!
That is awesome!!
