Fix a broken mop

It took me a few iterations to get it right. It works for the type of screw used in Spain. Please let me know if it works with the one in your country.

A piece of bamboo chopstick worked ok for me to hold the adapter to the aluminum tube. If not, an M5 stainless steel screw and nut would work too.

You want to print this part at 100% infill. I used a 0.8 mm extrusion width to make the part even stronger. And because the part is quite small, it will not take any longer than if you printed at, let us say 30%.
