Walker/Zimmer frame cup holder carrier

thingiverse

One of my friends requires a walker for the time being to move about after damaging her knee. Because she requires 2 hands on the walker it's impossible for her to be able to carry things like drinks or other small items, so I designed this to clip onto the walker's frame. This holder should be able to accommodate most mugs or cups, it has a slot for the handle to rest in and it has a spill tray to catch anything that might escape the cup during transit. It also has a small hook to hang a bag from and carry other items with. The frame of the walker this was designed for has tubes that are 22mm in diameter, the top part of the frame is two of these tubes together vertically which the holder sits around. I have included an obj file and a freeCAD file if you want to modify it.
