Walker Cup Holder Clip

My grandfather has been having trouble transporting drinks around his apartment ever since he started using his walker. To help him out I designed a clip-on cup holder that attaches to one of the rectangle bars of his walker. Thanks to the new assistive device he is able to go to the sink, and get water, and not risk spilling it or falling while using the walker. I figured there would be some other people who may want something similar, and hopefully can make edits to the device to fit more devices! In the picture, I have added the name of his walker to the plate, but left it blank in the published model to let you write anything you want on it!I have used 6x3 magnets to attach the plate to make sure it stays on, but can be removed quickly. The screw is what keeps the device attached to the walker, and the plate is for aesthetics.
