Still testing, PLA seems strong enough but I intend to print in PETG eventually. I'm 193cm (6'4") so this is probably a little long for others, shortening it would improve the strength.
Added .3mf as printing reference:for what worked for me: wall thicknesses, infill percent, physical orientation/layout etc.
I had to add another boolean to my library because of the nuts I chose to use with this, so be aware the huts are sold as square M3 5.5x5.5x2mm

But are physically 5.4x5.4x1.92mm (slightly smaller than the other more orange/coppery coloured square nuts I also have - image related)
There is however quite a bit of tolerance designed into the thing. Print the TOP part first and check that you can drop a nut into it, that it freely slides into it's side position, and the hole is aligned with the printed M3 hole.
Release and remove the grip from the pole. Using longnose pliers pull the elastic rope knot out of the top of the pole, and untie the knot. Release the elastic rope and pull out of the handle section...... Then reinstall the elastic rope into the printed handle. (yes this probably needs some explanation, but I doubt anybody cares, and anyone who does print/make this will probably figure out how by themselves)
