Remix of cane handle from @mastercaster. I am using this to convert a lacrosse stick shaft into a cane. The lax stick has an odd asymmetric octagon profile, so the shaft socket is redone from the original. The original also seemed to have some errors in the model that are now closed. I'm including the Fusion 360 (f3d) model file so you can change to fit your own weird stick.

This will be happiest printing with supports. I was successful in getting it to print fine at 0.28 PLA+ and with supports only touching the plate, so no need to excavate supports out from inside the socket. I used 25% infill but just about any should be fine. Will benefit from some sanding once the supports are removed.
