Drink/plate Holder for Crutch

grabcad

For the crutch accessory challenge. It will hold cups, cans, or bottles up to 8 cm diameter and plates up to 22 cm. (I don't know if it will hold 2 pounds of food but, if he is eating 2 pounds of food at a time, he needs to start dieting :) ) It hooks on the crutch handle and does not need a fastener. I am assuming FDM printing, though a fair amount of support material would be required. I cannot decide on the best orientation for the main arm - no orientation seems to provide strength in all directions - but would probably print it oriented as it is on the crutch. Cup holder and plate holder would be oriented bottom-down. Second arms would be oriented on their side.
