A fit built on real measurements, the same ones a vet would take. Whether you're a clinic fitting a patient or an owner caring for your dog, the process is the same: measure carefully, customize, and order a chair made for that specific dog.
Five simple measurements with a regular tape measure. Our guide walks you through each one.
The 3D model adapts to your measurements in real time. Pick wheels, harness, and a preview color.
One flat price. You receive STL files, an assembly PDF, and the bill of materials for the hardware.
Load the STLs into your slicer (Cura, PrusaSlicer, Bambu). Recommended print profile included.
Bolt the printed parts together with the hardware kit. Around an hour with basic tools.
Adjust the straps, let your dog ease into it, and watch them run again. Adjustments? Reprint a part.

Any FDM printer with a 200 × 200 mm bed handles every part. No multi-material needed.

"Rex hadn't walked in six months. We printed Petwheels on a Friday and he was chasing the ball by Sunday. I'm still in tears."
Marina, Rex's mom
"A vet quoted us R$3,500 for a wheelchair. Petwheels cost R$80 in filament plus the files. Same dog, same joy."
André, Luna's owner
"Our shelter has printed eleven of these so far. The parametric model means we never have to compromise on fit."

You can, using our guide and a regular tape measure. But an accurate fit matters. If your dog is recovering from injury or surgery, or you're unsure of a measurement, have your veterinarian take them. Vets and clinics can also order on a patient's behalf and keep each dog's measurements on file.
Pick the closest silhouette. The measurements you enter are what actually shape the model. If you're unsure, email us a side-profile photo and we'll suggest the best match.
Most cities have 3D printing services that will print parts for $10–25 in total. Search "3D printing service near me" or use platforms like Treatstock and Craftcloud.
PETG for everything is our recommendation: strong, weather-resistant, food-safe. PLA works for dogs under 10 kg. Avoid ABS for outdoor use unless you know what you're doing.
Because the files are delivered instantly, we don't offer refunds after download. But if anything is wrong with the files or doesn't fit your dog, email us. We will make it right.
The license is for personal use. Non-profits and rescue organizations can reach out for a free commercial license. We want these on as many dogs as possible.
Petwheels is a mobility aid, not a medical device. Consult your vet before use, especially for dogs recovering from surgery. Always supervise the first sessions.
Petwheels started as a final-year Product Design project at UFSC (Universidade Federal de Santa Catarina, Brazil) in 2021. The idea: use digital fabrication and parametric design to make wheelchairs for dogs with motor disabilities: affordable, custom-fit, and repairable.
A traditional dog wheelchair costs hundreds of dollars and rarely fits perfectly. A printed Petwheels costs the price of a coffee in filament, and adapts to every dog. That's the whole pitch.
