This is a compact extruder based on the cheap (both in price and quality) 28BYJ48 stepper motor. It was designed for printing flexible filaments via one channel of a diamond hotend.
Features:
Bowden tube out, guided in.
Flexible filament friendly: Bowden tube goes right to the gear+bearing set.
Quick release lever.
Lightweight: 63g
Compact: Stepper+square body = the size of a NEMA17 motor.
Known Issues:
Requires careful assembly, or the back cover may not fit well (aesthetics only).
No mounting holes, it just hangs on the bowden tube.
