Repair or replace the handle of cheap folding umbrellas.

Screws onto the m14x1.5 thread at the bottom of the pole. Print with Fuzzy skin on the outside circomference

The hole in the bottom is for a lanyard. The default one will fit. As will any suitable thread crimped with a simple wire crimp. 

I used a needle and thread, tied through the lanyard loop to pull it through the hole easily, as it can be a bit fiddly otherwise.

On my printer, I needed a bore of 14.3mm for it to thread on smoothly. Print a few of the thread testers first to get a feel for which one to print.
