Airtripper Direct Drive Bowden Extruder BSP Edition
Designed for 1.75mm Filament and Nema 17 Stepper Motor
This is the latest edition of the airtripper extruder series with many improvement tweaks and now is sporting a BSP fitting filament out feed socket.
The extruder has worked well with the MK7 drive gear and was able to push more than 3kg of force with stepper motor type SY42STH47-1684A.
I've not posted any information about the latest extruder design, however, the previous extruder design still provides a good reference.
