Crutch

I use less parts on this design (just 4 3D printed parts): - Cup holder : 2pcs 3D printed parts + rubber band, i choose rubber band since this is very flexible in any size of cup/bottle. I just use 1 pivot, i think during walking the cup/bottle will just move backward-forward, so i didn't put left and right adjustment. This is one of the rubber band sample : https://allensportsusa.com/products/parts/4-rubber-straps - Dish holder : I use the same concept with cup holder, but since this is not a liquid i put a stopper of back and forth movement of the dish holder, it will limit your dish to swing in proper angle, and to keep the disk in place i use soft rubber so the dish will be stick enough on it, this is some kind of that rubber : https://www.amazon.com/Length-Medium-Neoprene-Sponge-Rubber/dp/B01JSWJTNY/ref=sr_1_42?ie=UTF8&qid=1503363021&sr=8-42&keywords=soft+rubber I hope you like the design
