Can be adjusted for different sizes by screwing/unscrewing the parts and once adjusted just cut the endless screw tips and its done. Might need soldering of the endless screw to the bolts to improve strength.
Can be used with bicycle training wheels or with big printed Wheel. See pictures.
Dog's and Wheel Chair Story here: http://3dprint.com/18651/3d-printed-dog-wheelchair/


Big Wheel - Printed with PLA. Insert a GLCODE @pause instruction before the first layer of the top of the axis so you can put the ball bearing in place and let the printer finish printing the wheel with the ball bearing inside it. After putting the ball bering in place, put the extra ring printed on the first layer on top of it so the subsequent layer sticks more easily.
Example: for a 0,3mm layer, at the end of the layer 37 add:
G1 X0 Y0
this will move nozzle away and pause the printer so you can insert the ball bearing. An alert will show in Repetier with a button to "continue printing".
Tire - Printed with Flexible Filament but you can just use hight tension rubber tape around the wheel.
Can use bicycle training wheels instead of big wheel like in the picture.
Will include Instructions for the Fabric Bed soon.
1 meter of Velcro to fix the chair on the Dog using the "Velcro Holder" Part. (See Last Photo). Chest and Top Velcro.

Threaded Rod Diameter: 8mm + 14 nuts.
2 Bell Bearings External Diameter: 26mm.

Thank you so much for doing and sharing this!
I had an elder dog who had difficulty walking. Tried to build him a wheel chair with piping and training wheels, but it never worked properly. Quite sad thinking back how I never got around to making it work for him before we finally had to put him down.
I'm sure this will help some other dogs out there!

Thank You So Much.. I've hear these are Very Expensive!
Respect to all those involved in designing this for 3D Printing..

Amazing idea! Congratulations!

i have now also a dog how cant move his back balanced.
but he can move his feed he need some help to balance his back feeds.

one problem i see, is the treaded rod where the big wheel is connected to.
i think he would always run with this back feeds against this treaded rod.

i whant you to ask if you could mount this treaded rod to the top jointer?
i could use small bolts for the wheel and have for stability the treaded rod on the topjointer
where he could freely move his back feeds...
or just remove this treaded rod completly? would it be to instabil?

i would also need it mutch smaller, cause he is a little dog, more the size of a cat...
i think all half that size would fit for him.

i cant just resize it, cause then the hardware (bearings, rods...) would not more fit..

This is something I have thought about before but haven't met any dogs in need yet. Thanks for sharing!

Thank you for the reply.

Did you really just end up using the harness for the most part or is a fabric cloth under the belly?

Sorry the photos just don't quite explain it to me.

Dog I was making it for had to be put down :(

Figure I can finish it out and donate it to DFL

Hi,sorry to hear that. I used fabric under the belly. I have uploaded a picture with some instructions. Let me know if it makes sense.

A great simple design.

I would suggest fashioning "wheelie" bars on the rear of the chair in case you get an overly enthusiastic puppy who may just try to perform flips in his/her new rig:))

Thanks for putting this out there! I just started printing it today. I am going to scale it for my tri-paw weimaraner she is gonna be one happy dog!

This design is awesome! I am going to begin production tomorrow. Ironically this is what I was hoping to make from piecing things together. Thank you!!! Your a good person! I started a non profit rescue for PitBulls a few years ago and was inspired by people like yourself.

I'm interested in printing this for a dog-owner & his dog in my neighborhood. He would like to know: approximately how much did this cost to create including parts and filament?

Hi I spent BRL 19 on the parts (like USD 7). Not sure how much on the filament though.

This is fantastic. Really cool work.

Would it be possible for the fabric bed plans?

I need to make one of these for a special little dog I spent quite a bit of time with. It about broke my heart today when I saw her. I had no idea she lost the use of her back legs.

Hi, I don't have the design of the Fabric Bed yet. But it is pretty simple. you can do one like the on in the Photo or you can just use as set of wide velcros like the one in the photo I used for the chest holder.
