SmartRapCore (+Alu) Flex3Drive extruder Mount

thingiverse

This is a mount to fit the smaller version of the excellent Flex3Drive extruder (http://mutley3d.com/Flex3Drive-1/) to a Smartrapcore printer (alu and wood versions). Get a direct drive extruder but add only 85g to your print head. Please be aware the flex3drive is a part you have to buy separately. This was made by modifying the base of the kossel mini version of flex3drive which now forms the base of the extruder. I am afraid its a bit quick and dirty but it does work. If anyone feels like taking on tidying it up and making it a bit neater and less mashed up then I'd be massively grateful for the help. I haven't included the clip that holds the hot end as it's the same as the original smart rap core part so just use your old one. Print Settings Notes: Just print it as strong and accurately as possible. The mount to the print head will print with a little support the flex3drive extruder base needs no support. Post-Printing Some screw holes might need drilling. a little removal of plastic around the nut traps on the underneath. Use 2x m3x20 mm bolts to hold the extruder base to the hot end bracket. They should self tap. If using 1.75mm a short piece of bowden tube between the two parts helps guide the filament, make sure this guide goes up into the flex3drive and stops just short of the drive pulley. With 3mm it should be stiff enough for a filament guide not to be needed.
