Cup Holder for Walker

My son needs to use a walker after foot surgery. He asked for a cup holder. He has a walker similar to the "ProBasics 2 Button Folding Walker with 5" Wheels" as seen on Amazon.

I used the holder model for a Jeep Cup Holder by garyp53 and replace the attachment point with clips for the two horizontal bars. The bottom bar is 13mm. The top is 25.6mm and the space between the bars is 67.6mm.

Note, I printed upright with tree supports in cura, 10% infil. I used support blockers around the cup itself as the step out on the top half doesn't really need it.
