Flex3Drive for Kossel Mini – original tie rod effector

Here we present one of our much smaller designs aimed at the Kossel Mini Delta printer. This version of the Flex3Drive comes in at just over 30 grammes + the end effector. total weight a snippet under 50 grammes. The G4 (4th Gen’) Micro is a departure from the G3 family of extruders as we now have what we describe as front wheel drive. In other words the worm gear is placed in front of the wheel gear instead of behind. This makes little to no difference in performance but allows the unit to become far more compact.

The Flex3Drive G4 Micro for Kossel mini has all the same features as the 3rd generation designs but in a much smaller form factor. It comes with its own end effector, integrated hotend mounting and fan shroud. Its not just an extruder. We also have another version of this design here that offers steel ball or magnetic cup joints for those using a small delta with magnetic connection points.
