Sapphire pro 2 direct drive bracket/adaptor

thingiverse

Modified this slightly to work with the sapphire pro 2. basically redrilled the mount holes in the correct place, and thinned the back plate slightly so that the existing bolts between the extruder and the stepper motor reach and connect easily. So no new bolts needed. You will need to cut a length of the ptfe bowden tube to 105 mm. That links between the extruder and the top of the nozzle. Shorter or longer and you'll have filament feed issues :-) You will also find that the stock filament spool holder is worse than useless. Move it to the top of an upright and it will work with small reels of stiff filaments - but useless with a full size 1 kg spool and just way too much friction for flexible filaments. My next project is a better spool holder. The machine itself handles the extra weight of the extruder and motor, with no issues whatsoever - I can still rip off 0.3mm layer prints at 150mm/s with zero issues. If it wasn't for the spool holder issue - this would be the simplest and best upgrade you could possibly do :-)
