I love my Hurrycane, but it does have an annoying issue. It just isn't too stable in it's ability to stand alone. It is easily knocked over and will not stand alone on a carpeted floor. So I thought if it's foot diameter were slightly larger this might improve things. So this is the result. The new design is compatible with all the mounting hardware of the original (rubber feet, screws and bolts) so it's and easy exchange. It works much better with the new foot. It is much more stable and will even stand alone on my carpet. I was somewhat concerned about how it would hold up being used as a cane foot. I am bit of a large guy (207 lbs) and I lean hard on my cane. After 2 months of use it shows no wear or tear. Please be sure to print at 50% infill to insure strength.
