A friend wanted a wheelchair for their French Bulldog at limited notice. They ended up not able to afford the highly-priced business wheelchairs available on the net. I rose to the occasion to design a little something for an lovable dog, and the outcomes ended up superb. Murray liked her chair!
I’ve due to the fact built two other chairs for dogs, and I’ve labored on iterating on what I call the “FiGO” design and documentation to encourage dog house owners to deal with this job for their pet in will need.
This product uses parametrically developed 3D printed joint parts that match into acrylic or aluminum tubing. The tubing can be effortlessly personalized to the dog for the two match and style, and the 3D printed parts can also be customized through the Customizer application on Thingiverse. Currently screw dimension, tube outer diameter, wheel angle, and your dog’s measurements can be input to check out a rendering of your dog’s tailor made wheelchair. On the other hand, the typical parts are available for down load on Thingiverse. I’m performing on producing the parts resizable centered on your dog’s weight for extra strength (now you can do this by manually scaling the parts).
All the other resources utilized in the job can be sourced locally at a components shop or on the net on amazon.com.
one. Evaluate YOUR PET
In purchase to figure out what dimension your wheelchair body wants to be, you’ll have to measure your pet properly.
The diagram higher than depicts the a few measurements that will need to be taken. Measurement A is the width of your pet, measurement B is the top of your pet from the floor to the top rated of their shoulder bone, and measurement C is the duration of your pet from chest to tail.
Once you have these measurements, you’ll will need to do a couple uncomplicated calculations to figure out the lengths of tubing that will be necessary for your FiGO wheelchair. You will will need 6 parts of tubing, lower to the next lengths:
» 2 width tubes: measurement A plus 1″
» 2 duration tubes: measurement B minus the radius of your picked out wheel, then minus 1″
» 2 top tubes: measurement C minus 2″
I have established a uncomplicated Google spreadsheet that does these calculations for you as you input your dog’s measurements. Click on on File→Save a Duplicate to edit the file for yourself.
two. 3D PRINT THE JOINTS
Print all 10 of the joint parts, A–E (Figure ). You will print two each of A, C, D, and E these parts are identical on both aspect of the wheelchair.
The B piece will come in two variations, mirrored for remaining and appropriate sides. Print just one of each (the two information are offered on Thingiverse in the information part).
3. Establish THE FIGO Frame
Consider the two of your A pieces and a width tube, and slide an A piece on to each close of the tube. Make guaranteed the tabs that will be utilized for the straps are struggling with in the way pictured.
Following link both A pieces to the two duration tubes.
Slide both B pieces down the duration tubes leaving about 1″ or so between B and A (this will alter relying on your chair dimension, and you can effortlessly alter these parts later to match your pet’s dimension). Make guaranteed the tabs on the two parts are struggling with outward, and are the two pointing to the again of the wheelchair (toward piece A) as shown.
Now do the exact same with both C pieces, remembering that the tabs are on the outdoors of the wheelchair.
Cap both D pieces on the finishes of the duration tubes, with the tabs struggling with outward.
Place the two top tubes (measurement B) in both B pieces and then set your wheelchair body apart.
Now take both E pieces and the remaining width tube and link them jointly. (For dogs smaller than 10 lbs ., this step is not necessary you can print a distinctive version of piece E with no extra assistance bar.)
Hook up both E pieces to the base of the top tubes on your body .
Observe: After the FiGO wheelchair is comprehensive, the width tube among the two A pieces, as well as the top tubes connecting pieces B to E, can be glued with Gorilla Glue to make sure steadiness of the chair. This is not as essential when the dog is incredibly light-weight, but is suggested otherwise.
Make guaranteed you have extra your bearings to your wheels if they never currently have them. Then bolt the wheels to the E pieces working with the 3″ screws, capped with acorn nuts. You might will need to use a screwdriver and/or a wrench for this.
Eventually, include the straps . Both collars will be fastened to pieces D at the entrance of the chair, and the rest of the straps will be produced out of a dog leash (or any piece of webbing that you might have). Pieces A will have to have a extended strap, for the dog’s legs. Pieces B and C’s straps are for the dog’s belly and will will need to be the exact same dimension.
Reduce the dog collars in 50 % you’ll use the existing buckles to alter the match. Later you can lower them down shorter if will need be. The match will have to be incredibly protected.
To measure the human body straps, initially spot the leash all around the dog when it is standing in the chair, to see how prolonged these will need to be. Make the leg strap a little extended than the belly straps.
Reduce the straps with scissors, then immediately pass more than the finishes with a lighter to stop fraying. Once all your straps are lower to dimension, punch a hole into each close with scissors (the collar straps only will need to be punched at the finishes that you lower). Better nevertheless, use a soldering iron to burn up a hole by way of the strap. This will soften the plastic, blocking any fraying.
Protected the straps to the tabs on each joint piece working with the ¾” screws and acorn nuts, and make guaranteed they’re limited. (I utilized a distinctive sort of screw in the prototype shown listed here.)
Working with THE CHAIR
All dogs will take time to get utilized to their wheelchair. Some adapt definitely immediately and some loathe their chairs at first. It can take get the job done to train a dog to be relaxed with their wheelchair.
I’ve labored with a few dogs so much and I’ve professional: a incredibly relaxed and immediately tailored dog, an nervous and moody dog, and a timid pup. I’ve uncovered that leaving the chair in your dwelling room and just letting your dog strategy it and sniff it helps!

Significant: Consult with your vet if you have any thoughts or problems about the fabrication or match of the wheelchair.
