Dual X carriage for Prusa, Graber, P3Steel

thingiverse

X-axis, hotendholder and fanduct are remixes of toolson's MK2 P3Steel --> www.scheuten.me Printsize on X with a Graber i3 is 198mm. Note: The parts were not professionally drawn. All parts were created by "copy & paste" via tinkercad. Certain inaccuracies exist, but it works great. Required parts for the X axis: 4x MF126 bearing 1x 608Z bearing 2x headless screw M4x25 M3, M4, M6 screws and nuts 2x Hall Endstops & magnet Required parts for the direct extruder: Hobb-Goblin von E3D bearing 624-2Z Spring 2x Fan https://www.digikey.com/product-detail/en/delta-electronics/BFB03512HHA-AF00/603-1361-ND/2560485 or any other 35x35x10 radial fan M3 & M4 screws and nuts. The extruder files must be mirrored before printing for the right extruder. UPDATE: 11-02-16 : Add missing anti-wobble STL 11-05-16 : Add picture of "anti ooze aluminum sheet" for the parked Extruder, not final but works 11-05-16: Add bowden-version of carriage, NOT TESTED, I'm not sure if it's stiff enough, if not please give feedback. 03-21-17 Add "hotendholder_long_holes_right.stl", so now you can adjust the height of the second hotend, not nice but it works for me :) I use Marlin FW, there are only a few changes made in configuration.h and config_adv.h. https://www.youtube.com/watch?v=Hh3I1MQXOZI&index=3&list=UU2yeAK19aCaRl55bgDpe5Tg https://www.youtube.com/watch?v=Y0tNvyHmiu0&list=UU2yeAK19aCaRl55bgDpe5Tg&index=2 https://www.youtube.com/watch?v=hJZTBSODh6Y&list=UU2yeAK19aCaRl55bgDpe5Tg https://youtu.be/L047zwinpw4 https://youtu.be/htmuPwak5pQ Print Settings: Printer: Samella V2 (Graber i3) Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 20-25% Notes: Some parts need support, I used Simplify3d to generate this support. I have printed all parts with PETG, except the hotendholder, which is PLA (stronger) Post-Printing
