Puppy cart prototype 1
by caser, published
Problems I'm running into:
- I printed the draft in low quality, so I don't know how much of the structural problems have to do with the low quality, and how much is design flaw. (The rounded bar where the dog's legs can rest, connecting both halves of the cart are particularly flimsy.)
- The framing is 1 cm in width, which will have to be widened at least where the wheel axles go, if not around the entire frame.
- The cart is not adjustable, and is almost at the maximum size for printing. In order to make the frame work for the puppy as it grows larger, I will need to be able to create smaller, assemble-able parts to be printed individually.

Eddy's Wheels ( eddieswheels.com ) makes permanent metal carts, and various vets in the Northeast will do fittings.
This has inspired me to get a Makerbot. My dog has paralyzed legs from IVDD, and she is outgrowing her present cart. When I get one I will definitely try improving on this design.
I love cats but dogs (specially puppies) are OK too! It's nice what you're doing.
I'm still a complete newbie with 3D printing but I'm pretty experienced with FreeCAD and CAD in general. If you do give FreeCAD a shot, don't hesitate to ask me questions, or register to the FreeCAD forum (my nick there is normandc). I know it can be intimidating at first.
