PG35L Micro Extruder V3 - For J-Head
thingiverse
Version 3 is an alternative to the TrinityLabs micro-extruder body. This version has integrated bearing to appose idler tension. Use of the external bearing is no longer needed. The body is stronger and has M3 nut slots that don't penetrate the entire body. 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 body is designed for the eMinebea PG35L-048-USC0 motor. MendelMax 1.5+ kits and printed parts are available for purchase at www.ultibots.com. Alibre PE source files included. Instructions The idler requires M3-40 bolts and use M4-12 bolts to secure to x-carriage. Otherwise TrinityLabs vitamins are OK. You will need to remove and drill out the support layers on the idler and body. This extruder works well with AlephObjects Supa-Flat X-Carriage thingiverse.com/thing:10646 The bearing holders shown are:http://www.thingiverse.com/thing:15205, the last one on the download list.
