Ender 3 direct drive adaptor for FANG OEM duct assembly

thingiverse

This is an adapter for the FANG OEM developed by ozfunghi (https://www.thingiverse.com/thing:2763931). This adapter is still a work in progress because I've forgotten to design with the X endstop in mind. I've used a small piece of plastic to activate the endstop. With adapter v1, you will lose about 15mm and 21mm on the right of the X axis. v2 will be rotated a few degrees so there is no need for the tiny piece of plastic to activate the X axis endstop. You'll still lose a few mm on the right side. Also, I'll take into consideration cable management. Warning of v1 You have to cut a tiny piece of the FANG where the fan attaches. This is to avoid contact between the extruder shaft and the fang. I'll ask ozfunghi to adapt his FANG. To install, please follow these steps: 1. Unmount the old fan box or FANG design. 2. Unmount the hotend from the carriage. 3. Install the carriage plate + clip + extruder holder (+screws). 4. Attach the FANG to the carriage plate (+screws). (EDIT: Make sure the holes are lined up properly, and maybe it's best to squeeze the plastic parts together with your fingers while screwing so that the screw doesn't push them apart and snap the plastic parts.) 5. Slide the hotend + cables from the top, down between the carriage plate and FANG. 6. Slide the 40mm duct onto the hotend. 7. Mount the hotend + 40mm duct onto the carriage, from underneath the FANG and tilt it in place (+screws). 8. Screw the 40mm duct onto the FANG. 9. Screw the 40mm fan onto the 40mm duct. 10. Screw the radial fan onto the FANG (you can also do this before mounting the FANG). Be careful with the tiny screws. I suggest screwing them into the FANG before mounting the fan, back and forth moving forward slowly, just to make sure not to force the screws in, so you don't break the plastic and widen the holes just enough. Once the screw has pierced through, unscrew it, mount the fan, and safely screw the screw in again. No more stringing with PETG I've used the following settings: Retraction distance: 6 mm Retraction speed: 45 mm/s Coasting Enabled: Yes Z hop enabled: Yes Z hop distance: 0.2 mm
