after i posted last night i realised that my setup is 3mm and most people here are running 1.75, so i figured i might as well see if something similar could be done. it works… i center drilled a 4mm bolt, heated the end of the tube, and screwed it in. its not perfect, as my bit angled a bit while drilling. ideally i would probably machine an aluminum adapter and thread the tube onto that, but for proof of concept it worked pretty well.
