PG35L Micro Extruder V4 - For J-Head
by UltiBots, published
Version 4 is designed for short shaft PG35L-048 motors (8mm). This version has integrated bearing to appose idler tension. Use of the external bearing is no longer needed. Also, this body has a snap-in slot for a J-Head hot end which eliminates the aluminum slot plate. The snap-in idea was derived from scottmayson. This Micro Extruder has been tested on MendelMax and Prusa.
