M14 Umbrella Handle - Customizable

This is an umbrella handle for umbrellas with an M14 or M14-ish thread. The thread size is based on measurements taken from my broken umbrella and the thread, which was made out of rubber, is oval, and seems to have a roughly 14mm widest diameter and a 1.5mm pitch. 
It's been tested with the ok.- umbrella and worked well for this one.

There is a “Loose” version of the handle too with a 14.4mm diameter thread if the regular one is too tight for you. 
And if that still doesn't work for you, you can customize it in Onshape and choose any thread size and pitch you like. You can change the thread parameters in the configuration editor in the top left. When exporting as STL make sure to select millimeter as the units.

Features

There are some other umbrella handles on this platform but all of them seem to try to replicate the injection molded design with thin walls and ribs. This design aims to be beefy and robust.

• Strong and beefy

• Slightly longer than my umbrella's original handle for comfort

• Slightly concave shape for comfort

• Textured for better grip

• Dual lanyard hole that supports loping through the two small holes or using a lanyard with a stopper knot or clip fed in from the top

Printing

Print the model in the original orientation. All STLs are pre-rotated for printing. Use thick walls for a strong handle.
