PG35L Micro Extruder V5 - For J-Head

thingiverse

The Version 5 Micro Extruder is designed to accommodate both short and long shaft PG35L-048 motors. It comes equipped with two integrated bearings to counteract idler tension and minimize shaft wobble. The extruder body also features a snap-in slot for J-Head hot ends, eliminating the need for an aluminum slot plate. This extruder has been successfully tested on MendelMax and Prusa printers. A recent design change positions support bearings closer to the PG35L motor for increased surface contact with the Drive Gear. To use this version, download me_body_v5_3mm.stl. Additionally, a Buddaschnozzle version is available. For more information and to purchase Hobbed Drive Gears and Bearings, visit www.ultibots.com. The site also offers MendelMax Kits, Printed Parts, Filament, Electronics, and more. Alibre PE source files are included with the design. To assemble the extruder, you will need M3x30 bolts and M3 jam nuts (x2) for the idler, M3x25 bolts and M3 jam nuts (x2) for the motor mount, 624ZZ bearings (x2) for the internal body, a 624ZZ bearing (x1) for the idler, M4x20 bolts and M4 jam nuts (x1) for the idler bearing, M4 washers (x2) on either side of the idler bearing, M4-20 bolts and M4 jam nuts (x2) for the internal bearings, and M4 washers (x2) on either side of the internal bearings. Remember to remove and drill out the support layers on the idler and body. For gear removal assistance, try our gear puller available at thingiverse.com/thing:31660. On January 13th, v5.1 was uploaded for use with 623ZZ bearings, using M3 hardware. A version without the J-Head snap-in was uploaded on January 14th. The 624ZZ idler and v5 body for 1.75mm filament were added on January 22nd, with corrections made to the snap-in slot on February 11th. On March 31st, a v5 body for 3mm was uploaded with mounting holes centered on the filament hole; however, it remains untested and may have interference issues with the PG35L motor mount holes.
