***Modified versions of Original Prusa Mk3 Extruder for the CrusaXY HB1*** ***Will be updating with additional purchased BOM, pictures and printing instructions*** Link to [CrusaXY HB1](https://www.thingiverse.com/thing:3705247) Motor gearing is 3:1 with chevron gears and slots for square nuts in gears. Both gears have a 5mm shaft. **Printed Part lists and descriptions** *extruder-body(R3) Bowden V6* - Uses the e3D V6 extruder with bowden collet (removable threaded pneumatic coupling). **Use this for CrusaXY HB1 First Extruder** *extruder-body(R3) Two Way Fan* - Allows for heatsink cooling fan to be mounted on both left and right side of heatsink (only one is needed). Uses the Original Prusa i3 V6 heatsink with integrated collet. *extruder-body(R3) Two Way Fan Mirrored* - Same as previous, mirrored so idler bolts face opposite direction. **Use this for CrusaXY HB1 Second Extruder** *extruder-body(R3) Two Way Fan and Bowden V6* - Allows for heatsink cooling fan to be mounted on both left and right side of heatsink (only one is needed). Uses the e3D V6 extruder with bowden collet (removable threaded pneumatic coupling). *extruder-body(R3) Two Way Fan and Bowden V6 Mirrored* - Same as previous, mirrored so idler bolts face opposite direction. **Or use this for CrusaXY HB1 Second Extruder** *extruder-cover(R3) Two Way Fan* - Cover for corresponding body. *extruder-cover(R3) Two Way Fan Mirrored* - Cover for corresponding body. *filament sensor cover Reverse Bowden* - Filament sensor with integrated threads for PC4-M10 pneumatic coupling. *filament sensor cover Reverse Bowden Mirrored* - Same as previous, mirrored for corresponding body and filament path. *filament sensor cover Reverse Bowden Cut Shorter* - Filament sensor with integrated threads for PC4-M10 pneumatic coupling and cut shorter. **Use this for CrusaXY HB1 First Extruder** *filament sensor cover Reverse Bowden Cut Shorter Mirrored* - Same as previous, mirrored for corresponding body and filament path. **Use this for CrusaXY HB1 Second Extruder** *Motor Mount for Gearing* - Mounting plate for motor relocation and geared drive shaft support. **Use this for CrusaXY HB1 First Extruder** *Motor Mount for Gearing Mirrored* - Mounting plate for motor relocation and geared drive shaft support. **Use this for CrusaXY HB1 Second Extruder** *V slot Gear V1.2LFT EXTRUDER* - Chevron gear for motor (**driving gear** Num teeth LFT=1). *V slot Gear V1.2RGT EXTRUDER* - Chevron gear for drive shaft (**driven gear** Num teeth RGT=3). *NOT INCLUDED BUT NEEDED* - Original Prusa Mk3 extruder idler (R2) or (R3) for corresponding extruder body and nozzle fan for print part cooling.
