cults3d
I've been in need of a filament roller guide that allowed to feed from both top and bottom into the extruder , without any extra resistance so I designed this : Ender 3 double filament roller that allows feed from both top and bottom ! No extra hardware required . No supports . Quick print . Tooless assembly . Feeds from any direction without extra resistance ! Prints in one go . It will last for a lifetime ( mine is over 150 hours , no lube , no bearing , no noise ! )
