Flex3Drive Dual Nozzle

This is our unique Dual Nozzle Flex3Drive compatible with any reasonably well built 3D printer. The sturdy design includes integrated mounting points so there are no extra adaptor plates or fidgets required to install this onto your machine. Just a carriage with a simple mounting footprint pattern is all that is required. This dual nozzle design includes our original rigid two-bar filament tensioner system that allows quick filament changes and gives reliable repteable tension every time. We also supply a pair of optional screw based tension arms to allow for fine filament tension adjustment for some of those filaments that may require it.

The Dual Nozzle Flex3Drive is compatible with all common hotends and comes with its own dual 25mm hotend cooling fan assembly that simply slots into place without fasteners keeping your hotends as cool as ice whilst being easily and quickly removable for maintenance purposes should the need arise.
