Two Trees Sapphire S Direct Drive & E3D V6 Hot End Mount (Prusa R3 Remix)
bymintytreborModel originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3669759.
This mod enables the mounting of a stepper motor and extruder directly to the x/y carraige of the Two Trees Sapphire S CoreXY printer, plus the brackets for an E3D V6 Hotend. The mod includes a remix of thing 3396264 by 2bedom, which is itself a remix of the MK3 R3 mounts.
This mod also includes components from : https://www.thingiverse.com/thing:3249344 - Mk3 Nozzle by RH_Dreambox https://www.thingiverse.com/thing:2758290 - BL Touch Mount by m3lvm
Features and changes include :
Enables stepper and extruder to be mounted directly above V6 hot end, to eliminate the poorly implemented original extruder/bowden configuration. Technically there still is a little bit of visible bowden between the extruder and hotend, but this is necessary to accommodate the frame.
Adds 20mm+ to the available Z build height by raising the hot end mount position, all other build dimensions remain the same.
Replacement of 5015 50mm fan with a 4020 40mm fan for part cooling - This fixes the issue of the 5015 fan colliding with the front right axis rod at the extreme of its travel.
Added cable support to extruder mount, to better support main wiring harness (requires zip tie)
Update 04/06/2019: Added V2 of the extruder mounting bracket, which has improved strength and new cable management features to allow all cables (excluding thermistor and hot end power) to be constrained above the xy carriage rail, which reduces the possibility of any cables rubbing on the z axis screw.
Update 16/06/2019: I have modified the nozzle to accept a vertical 5015 set 90 degrees to the v6 mount, this allows a 5015 fan to be used without compromising the build volume on the X axis. This change also includes a new fan support bracket. Using a 5015 fan delivers better part cooling air flow. (I will be the first to admit its not visually appealing, but it is functional and an improvement over the 4020 fan solution)
