Tornado/MK3S Bondtech Geared Extruder-Direct Drive, BLTouch, Filament Sensor

thingiverse

This is a remix of the Bondtech Geared "Prusa I3 MK2.5S / MK3S Extruder upgrade" to work on a linear rail and the stock FlyingBear Tornado (Gen 1) steel carriage plate. https://www.bondtech.se/en/product/prusa-i3-mk3s-extruder-upgrade/ The original upgrade kit uses: - E3D v6 hotend - 25mm NEMA 17 pancake stepper motor (direct drive) - Inductive bed leveling sensor - Optical filament runout sensor - Part and heatsink cooling fans I have modified this to attach to the carriage plate mounting screws on the Tornado, allowing space for the carriage plate-carriage hex heads that stick out. I have removed the inductive bed leveling sensor and switched it to a BLTouch as most of us use glass beds. If you can afford it, I recommend buying the gears and parts from Bondtech, as they took the time to develop these excellent designs. Their build quality is also top-notch.

This remix uses a BLTouch instead of an inductive bed leveling sensor, as most users have glass beds. You can purchase the gears and parts from Bondtech or TriangleLabs. Note: This is a work in progress. I would appreciate all feedback in the comments section. *Changelog:*
