This is a collection of assorted cane toppers that I had custom made for some friends of mine. I thought I might as well post the lot here so that anyone who needs or wants one may use them. All of these canes are designed to fit a 1 inch dowel, which may be purchased at a local hardware store in 48 or 36 inch lengths. They may or may not need to be converted to metric, however the latest version of cura has a built in "Barbarian Plugin" that will do it for you.
10-25%, depending on the usage.
A good way to increase the strength of these parts without using a lot of infill is to increase the number of perimeters from 2 to 3.
