Wheel chair seat rail guide

thingiverse

We purchased this wheelchair for my sister from a second-hand store, allowing her to attend Comic-con following her foot surgery despite the broken seat rail guides, which we hastily repaired. A couple of years later, I now own this printer and my parents are giving the chair to a friend, but they didn't want to include the makeshift bracket I created, so I designed new rail guides for it. I used Tinkercad to create these new guides since I have no experience designing objects. The rod that fits into the seat tube is 19.5mm by 18.8mm (.76 x .74 inches) in size. The part that attaches to the rail measures 21.6mm in width, allowing it to securely grasp onto a 22.3mm (.88 inch) diameter rail tube.
