Is it compatible with a hamster?

I just wish this wouldn't take so long to print! My cat Simba would look amazing in it!

Anyone have suggestions on how to print so that it wouldn't need so many supports??

I just finished mine but i can't seem to figure out how to share it

never mind I got it

That is so cool but my cat would never wear that ;)

i must say this armor is challenging for me to print on my small prusa i3 printer. so i might release an eco version of this model with smaller parts you have to glue together.
J Wall. what do you think? i will give you the credit that you deserve from this awesome model! but for the small printer owner like my self. it would be a great help for others to print aswell! :)

Hey APC! Thanks for the love! Thinking about getting one of those printers as well. Yes, feel free to remix the cat armor however you need to and add attribution. Only don't sell the armor as your own. See license details below:

Thanks for commenting and remixing! #HappyPrinting

oh i don't take money for it :D planing to give it away for Christmas present :D

Does it cost a lot of money in filament?

Planing to print this is Prima select Gold pla. I Will post pictures!

nice, but i think my cat won't love it. do you'r cat Opposed to the armor? i will be happy if you gonna answer me, Thank you!

Can you please add a list of how many of the print parts i wil need?

Thanks for the love William!

Just out of curiosity, did anybody scale this build at all, or does the default 100% seem to fit most cats?

Their performs are given the thing never to provide an idealistic watch but to identify where lighting along with the natural environment are important. ..i like it so much

Thanks for the love! :-) :-) :-)

Hi! The cat armor is so cool! I am new to this, and my library has a Makerbot 3D printer available, so I'd like to print this armor for my cat. I am worried if my cat is too big for this design. He is 15-16 lbs, about 14 in. from shoulder to base of tail (he wears medium sized dog costumes). I saw one of your earlier comments mentioned your cat being 9 inches from shoulder to tail base, so I am assuming lighter and skinnier than mine. How wide is the armor? I think the Makerbot printer might allow me to resize a little larger, so should I do that, or print an extra middle segment or 2? Any advice would be great. Thank you!

Comments deleted.

I downloaded this thing and tried to print it, but every time i tried to print the chest/shoulder plates i got a notification saying it was off platform and wouldn't let me print. Any help? (using Dremel3D)

How does the front chest plate attach to the shoulder plate? I see the pegs, but they don't line up properly and I see no way to get them to stay there. Not really wanting to glue in place.. Thanks for creating this by the way!

Hey! Like your profil pic! The pegs should just hold it up. Im out of town at the moment so.im.not near the cat armor to look closer at it. It should just rest on those pegs. Feel free to modify the design any way youd like to work best for you! Hope this helps. Ill try to get back to you with more once I get back home.

Found this by Google auto search.
This dressing animals up sort of thing feels wrong to me.
Do what you want, but if you want to defile cat-kind
with this junk at least know this
•the cat will get snagged in thorny brush
•The armor will negate any tail-based special ability
•it affords no protection against bunny-kicks or spellcasters

Thank you for this amazing design! My cat used to laze around the house and do nothing all day! Now that he has his own set of Cat Armor, he's been reinvigorated! I'm going to sic him on the rottweiler down the street right now! Thanks Cat Armor!

Hahahaha! You are very welcome! Be careful. ;D

I have printed the chest piece twice now and it seems that the ends of it (where the holes are) are really thin.
When pulling off the supports I used to print it, it cracked.

This also makes me concerned as to the durability of this part.

Is there any way you can make the walls slightly thicker?

jtrezzo - in reply to tommckearney

I had the same problem. Had to switch to a .3mm nozzle for it to even print anything on the shoulder piece ends. Tried in Simplify 3D and Mattercontrol and walls would just be nonexistent in those parts on the ends, near the spot for the pegs. Wish there was a way to post pics of what I mean.

This was with Cura and 20% infill.

I sliced it with Slic3r and added a modifier to change the problematic parts to 100% infill and that seemed to make it better.

Yes! Thanks Tom. Will do.

When I downloaded this thing I downloaded 18 STL files, however, 3 of these STL files are blank. I am missing the three posterior body plates, which I believe are the blank ones. Is there any way you can email those to me? Or fix it on the website?

https://gumroad.com/ptt you can download a zip of the files here for free

you should update the thingiverse prints

I don't understand which files to download. Clicking the "Download this thing" button gave me three blank .stl files. So... which ones should I be downloading? Are there some that you print multiples of?

Hey J Wall, I was going to start printing this for my miniature dachshund but upon loading these flies I discovered that they are too large for my print bed. I was wondering if you could possibly make a version of the armor that has the main armor pieces split in two. It would be great because my build platform would then be able to fit the pieces. I would love to see her run around the house in this. Please consider.

Hey! That would be great! Please feel free to adjust, cut, scale, or edit the files to fit your printer accordingly. I used a MakerBot Replicator 5th Gen.

Do you have a list of how many of each part needs to be printed to complete the project?

I only have the photos you can use for reference.

Would cars like this

Cars... not sure. Cats... not sure... either

How big of a print area would you need for this? It looks so cool I just hope I'm able to print it!

large-ish. like 5-6inches

Could you make dog armor???

Do you know if you could make an option that does not have the spikes? I would love to have this for my cat but I don't want her to scratch anyone with the armor simply by brushing against them.

Hey! Feel free to change the model anyway you need to fit your furry friend's needs!

When my cat saw this thing on my computer the cat try to kill me !!!

HAHAHAHAHA! Thanks for showing your cat. Doesn't sound like they want to wear it :D

Pondering taking this and adapting it for the bunny.

Hahaha! Would LOVE to see a photo of that if you do.

Well, it will take me a bit to be in a position to try, but if I pull it off, or anything close, I'll post a pic. Other than sizing, I wouldn't think there'd be too much adjustment required...and maybe shorten the tail a bit.

What would i need besides 3d printed parts to make this?

a cool cat! Maybe some brass fasteners.

Do you have any suggestions for brass fasteners? The pegs and stuff are difficult to print

Thanks for the love MayorFugs!

That is very cool cat armor! I hope to print it some day. would you mind telling me what program you used to design it?

Hey Pattridge! Thanks for the love! I hope you print it one day! Would love to see photos if you do! I modeled the design in Cinema4D

My cat is strangely small - most likely due to her heart murmur, she's just stopped growing. Would the armor probably still fit her?
Also, what is the total printing time?

Possibly! :D It's roughly 4-6 hours per large part on low resolution. Plus the time for the smaller pieces.

All hail "SpartaPuss" - slayer of a thousand mice!!!

How many grams of material does this set up take?

665g (1.5lb) of PLA

That's awesome sauce.

Thanks for the props!

I have a question regarding the orientation of the parts. For example, if ARMOR_0_CHESTPLATE_fixed is rotated so the back rests on the bed, there is less support material and much shortened printing time. Is there some advantage to printing the files in their current orientation?

Hey Miles1999, Feel free to turn the pieces however you like. The file's default orientation is not necessarily the best printing orientation. I'll update the files for what I had best luck with soon! Thanks for checking out and commenting!

My cat actually got in a battle with me, and I forgot to put on my 3D printed Minecraft diamond armor. (The cat won!)

Comments deleted.

Do you think this would fit a small pug? Awesome build!

I think so! My friend put it on her dog the other night at a 3D Printing Meeting. Check it out here: http://go3dprinting.tumblr.com/post/133735427621/b3dge-by-emilysuelaird-brenda-looked-fierce

Hi! I hope there's still some time for helmet designs! Here are some sketches of my design ideas. I'm not a 3D modeller, but I hope these are workable/wearable or at least provide some inspiration!


"The Oni" takes your existing armor design and adds a stylised Japanese demon helmet to make your kitteh look badass! The nose-piece could possibly be detachable.

Who needs the eye of the tiger when your kitteh can have the "Eye of the Scorpion"! The purrfect addition to a scorpion tail is a scorpion helmet with rounded scorpion eyes so kitteh won't hurt himself/herself while cleaning. Defensive and safety conscious!

Lastly, is the "Battle Kitteh of the Universe"! Loosely based on a famous fantasy cat from the '80s, this helmet will transform your kitteh faster than you can say, "By the Power of Catfood!"

Enjoy! :3

Hey Craig! Bobo and I designed your helmet!!! https://www.youtube.com/watch?v=7ENleqsk9UA

Thanks so much for the inspiration! Blown away with your designs. Please message me a mailing address you'd like me to send the entire Cat Armor and Helmet to you. You rock!


WAAAA! So awesome! :D Thanks so much, Jwall! Love that video! I'm really happy that you picked the "Battle Kitteh of the Universe" version. That was my favourite too (sorry that Bobo didn't like wearing it! lol ;) )! I've sent you a message with my address. I'm going to be grinning all night and telling all my friends to watch your awesome video!

Craig / Sunstreaker

YES! That looks incredible! Thanks so much for the submission! WOW! :D

You're welcome, man. Thanks for coming up with such a great idea in the first place! It inspired me to draw some cat helmets, so I hope my drawings will inspire someone else as well. :3

al tratar de imprimirlo en escala %73. las paredes de la armadura quedan tan delgadas que el cura no los imprime
es una gran armadura y protegerá a mi gato del gato de mi vecino, podrias modificar las paredes para que sean por lo menos 1mm mas gruesas?

Hey! Thanks for the notes. Yes, I will adjust the wall thickness on all pieces as soon as possible. Still a work in progress! :D

I almost want to get a cat to put that on it.

Ok, this is a very good job, but I like to know what you took to put this on your cat?
I think it's not a very good idea ... if I do the same for you in a style that may not please you you'd be willing to wear it?
I find the idea a little "limited" ... borderless.
this is MY opinion ... ^^

That's a good opinion. Thanks for commenting.

Being leader of the Cattopia located in Sector 77, I believe my warriors will love this new armor design. We look forward to coming to your planet for the rapture on December 8, 2098. See you soon ;)


Looking forward too! Meow!

Um I have a idea for a helmet.

I think it should be very cool to see the cat armor helmet to be based on the ""dark helm"" from a show called" my little pony" the user of this helmet is "nightmare moon" (puny) and also by eon ( my pony character and I do have him but I only have the dark helm on my eon and Bianca trophy and faintly on my eg human eon, you want to check it out) if you think that may or may not be a good idea I whould really appreciate it if you tell me your opinion.

Thanks, Eonbrony.

Also I am posting this on a iPad at 11:33PM so I can't post the links to eon and Bianca trophy or eg human eon until I get access to a computer. One more thing. If you are interested in this idea and just want to get the dark helm I will gladly get it for you and it really works great (would) with the design of the cat armor you made

it is now 9:58 am and I have the eon files

I deleted the eon files and replaced it with the dark helm to make it more relevant.

this is the dark helm

dark helm cat helmet

That's AWESOME! Really dig how you designed the hat! Props & Respect!

I would really like it if you use it. :) add it to this thing. or something

Does it protect against cat burglars?

of course it does! :D

My Mini Kossel kit didn't come with a cat. Damn.

By the power of Grayskull! This is pretty cool. :)

you mean sunbutt :3

YAAR!!! :D :D :D

WELL DONE super cool idea! could you please upload a basic helmet model that we can edit? since for me is difficult to estimate dimensions of the cat's head.thanks

I don't have one yet. We're asking for people to collaborate and we'll 3D design, print, and gift the armor to the selected designer. Thanks for the support Everik99

Well done! Your photos are as great as the design.

Thanks for the support rh3d!

I would suggest taking a look at He-man's Battlecat armor. That helmet even has spikes similar to your awesome armor.

Noted! Love the idea!

This is great! My cat normally gets a little spooked when I ride her into battle but with the armor I should have no problem! Also, with the spiked tail she's sure to take out a couple of lesser goblins while I focus on the larger orcs.

Hahahaha! :D :D :D

you sir are amazing

Thanks for the love. Much more fun to come!

Totally cool! I want to modify it to fit my bearded dragon!

please share the desing for my dragon too!! :P

Great work!! Meow my cat can look like a total bad ass!

Hahahaha! Meow you're talking!

Dananananaananananana! :D Thanks for the suggestion JoshuaJ. Love batman!

Thats not a cat, its a dragon.

Bahahahaha! :)

It is a very nice idea Bobo looks like a Klingon cat in the video..
Qapla !

Thanks for the love, Bobo's The Dude!

This is too awesome for words.

I must agree with you completely

It looks Majestic! I don't own a cat but 2 dogs, however this certainly does look like something I would put on my cat if I had one! great job

Dog armor could be cool too! Haha! Thanks for the support

I'm so gonna do it for with my printer coming in

Awesome! Which printer did ya get! Congrats is a very fun and addictive hobby! Haha

Hey there buddy. I'm sure it will be fun. Not too sure about the model of the printer as its custom made from Singapore by my buddy. Pretty good in my opinion. Every spare parts can be even printed to replace.

Thanks for the love!

I have quite a few things in front of this to print but is definitely in the queue, sadly business before play :(

I completely understand. Haha! Thanks for adding it to the list ;)

Awesome job!

May I ask how big/old your cat is? I was wondering if the armor will suit my 6kg year old kitten.

Can I suggest the gladiator mask for completing the cat's armor? or maybe !!!I'm BATCAT!!! kind of mask.


Thanks for the love danielfox! My cat is 1.5 years old, about 9 inches from shoulders to the base of his tail. Love the idea for masks! Really appreciate the suggestions. Send me a photo if you print this for a kitten.. PLEASE! :D

that is awesome.. I have to make some

Awesome! Would love to see a photo of you do. Let me know if you have any printing questions. :)

I was going to say Battle Cat too:-) This is great. Bobo is a beautiful and very co-operative kitty

Haha! Yeah, didn't even realize the battle cat resemblance, but so happy it does. I watched He-man like crazy when I was a kid! Gotta love the subconscious. Haha. Thanks for the love on Bobo, I agree, he's one cool sexy cat.
