This is a remix of the shaft for XT60 plug without screw hole to attach it. Just solder the wire to the plug, push into the shaft and use hot glue in the hole for securing the plug.

I designed also the main box since my card from Aliexpress (https://www.aliexpress.com/item/32966317113.html?spm=a2g0s.9042311.0.0.73494c4dMn0u71) did not fit exactly the original. Thanks to Volker for sharing its 123 file. I kept the cover from its design.
