hi fellas
this is my funnel design for great Lyman Filament extruder. I greatly appreciate his effort on improving his piece of art.
this is what i designed for my filament extruder as i used 3/4" pipe and I wanted it to be firmly attached.
to assemble use:
M5 X 20 screw 4pcs
M5 Nut 4 pcs
hope it's what you're looking for, just like me.
