Extruder for Prusa MK3 with E3D Revo Micro and Orbiter 2.0

thingiverse

This is my new extruder for Prusa MK3 featuring E3D's Revo Micro and the new Orbiter 2.0. For download I added the complete assembly in step-format. Free to further develop these data. For printing I added amf-files. The Orbiter needs different settings which are all described in the documents coming with the Orbiter. I used a 25x25x6mm hotend-fan with a 3-wire lead which prevents problems with the Prusa firmware. It's a SUNON KD0502PEB1-8 which is quite hard to come by. E3D ships a 2-wire hotend-fan (20x20x10mm) with the Revo Micro hotend. For anyone looking for another fan: The hotend-fan needs a maximum airflow volume of at least 1.9 CFM. For the 3 main structural parts (x-carriage/x-carriage-back/adapter RM-Orbiter 2.0) I used ColorFabb PA-CF because you need optimal stiffness here. For the M12x1.5 thread in the Orbiter/Revo Micro-adapter it's advisable (at least for PA-CF) to use a cylindrical speed modifier area (PrusaSlicer) around the thread to reduce the speed locally to 12 mm/s. Layer height for PA-CF: 0.2mm/0.4mm nozzle(X). Other filaments: Extrudr GreenTEC PRO (print fan shroud, hotend fan holder, Pinda mount), PLA (remaining 2 parts). 2 parts with 0.25 nozzle/0.1mm layer height: hotend fan holder, Pinda mount. Remaining parts with 0.4mm nozzle/0.15mm layer height . Supports only for print fan shroud (3 air exits) and hotend fan holder (arc). If anyone needs more information please ask me.
