DIY pet wheelchair, using 3D printed connectors and aluminum bars.

See it in action here:

I'm developing a cheap DIY wheel chair, that's can be easily customized and scaled to fit any disabled pet. There are three 3D printed parts, and each needs to be printed in two copies (some files already have both copies aligned):

HortiVerticalAdapter (X2) - This piece connects the width bar with the two length bars.

WheelFrameBandConnector - This piece sits on the length bars and connects each to a wheel bar. It's also the basis for the rear saddle.

BuckleConnector - This also sits on the length bars, and is designed to connect to a buckle, which will attach the wheel chair to your pet's harness.

The original dimensions of these 3D printed parts are designed to work with 1cm wide, 3mm thick bars. The two length bars and the two wheel bars are 30cm long, and the width bar is 20cm long.

EDIT: I added new files that should fit nicely with 12mm aluminum bars as requested (it appears 12mm is much commoner and easier to acquire in Australia. Cheers!).

Want to make one of these.....was approached by a woman whose cat was losing its 2nd front leg to cancer.......the vet told me a front wheel cart was not a good idea due to their spines (plus the animal was far worse off than the owner wanted to accept).

Ugh.. poor little thing..
Unfortunately this rig will be of little help for missing of disabled forelimbs.
It's designed so that the critters hold their own weight using their front legs, when their hind legs are disabled or missing.

What you probably need is a 4 wheel cart that has room for the rear legs.

Hi all,
I stumbled upon this website after googling "cat wheelchair" for a while.

First of all, thank you for sharing your design!

We've recently adopted a cat that we rescued from China (this is her story of getting her here to UK: https://fundrazr.com/campaigns/410hi3?utm_campaign=team-action-item-FUNDRAZR_ACTIVITY&utm_medium=email&utm_source=03-2016)

Persia Marie can't use her back legs, so I don't know if this wheelchair would work for her, but it's definitely worth a try!

My question is, I obviously know nothing about 3d printers and wouldn't even where to start. How can I find someone with a 3d printer here in UK? Any ideas how much this costs?

I'm sorry for the stupid questions.

@Morliac, I'm so happy that Mozart can move again!



Hi Eva,

Hope this design can help your cat!
It pretty likely you can get help printing and building this wheelchair in a local makerspace.

Try googling your city or area + "makerspace" and you're bound to find one close by.

The cost varies according to the amount of material and time it takes to print, and of course depends on how much the printing service will charge by these parameters. In this case all parts should cost ~50$ and should take no more than 12-16 hours to print in total.


I will definitely look into that! We also bought her a life jacket - will try to do some physio with her at the same time. She's a sweet kitten, so I definitely want to give her the right wheels!

Will post updates here.

Thanks again!


Have you had this 3D printed yet? If not, I would be honored to print the parts and ship them to you for Persia Marie.

Best regards,
Brandon F.

Hi Brandon,

Thank you for your kind offer. I haven't had any luck so far, so would really appreciate your help with this!

edieblu, my email is the same as my username at gmail.com. I'm already working on the printed parts, but would like to coordinate details with you. Please email me.

I've just emailed you:)

I replied to your email a few days ago; please check that it wasn't filtered as spam. The printed parts are finished.

I used this design to help my cat recover from 2 broken legs after falling off the 6th floor, and he's doing much better.

The story actually made it to the media:

That is so utterly awesome. Thanks for posting this! :)

It would be more awesome if the appropriate credit was given.
3DHubs' Sydney Maker's Hub printed the wheelchair but there's no credit given :/

great work!

(i need something like this for dogs in all different sizes...)

Thanks :)
I'll release a larger version soon which fits small to medium size dogs, and you can scale the 3D files and edit them as you see fit.

I like these pet assistance devices but I wonder, is there a means for the cat to sit or lay down? Do you need to take it off so the cat can rest? Would be perfect if the cat could learn a motion that retracts the wheels and allows for laying down.

Comments deleted.

That's a good point, though the problem is different - The cat can sit down with the chair on, but since his hind legs don't work, he can't get back up by himself after sitting.

Ideas for how to solve this are welcome :)

you could make it so the wheels can go back a bit for when the cat moves forward but when it moves back the wheels move forward all the way so it can sit or lay down

That's an interesting idea Maximus,
Although, as previously mentioned, he can sit down if he really wants to, but he can't get up by himself afterwards...
