Custom ski pole handle. I think it's not the best idea to 3D print the handle directly; I made a mold and used Modelite - it can be a bit brittle, but if you get the pole along the entire length, it's strong enough. You could also use something like Silicone.

You can customize the Inventor mold file, but it's easier to update the pole adapter. I've included a customizer. Just set the diameter to your pole size (in mm) - the adapter then fits in the mold - it also adds support to keep the pole level in the mold while the handle material hardens.

The handle goes with the basket to make a complete pole using any pole material you have on hand. http://www.thingiverse.com/thing:1296332
