--Simplicity 5015 Cooling Fan Mounts and Duct-- This is a highly efficient, effective, quieter setup that allows for quick and easy access to maintain the extruder. You may want to run the parts cooler slower as this fan is stronger. --Simplicity Easy Direct Drive Conversion-- I have included my custom direct drive mount that rotates in reverse direction from stock. China sent me the wrong alloy parts so I had to re-pin the connector at the board to run the stepper in reverse. Swap the two outside wires for each other and then swap the two inside wires for each other. Do them two at a time to avoid confusion. Ideally, you can just download a compatible direct drive mount that doesn't require any reversing mods. For example, you can try: https://www.thingiverse.com/thing:3998501 or https://www.thingiverse.com/thing:3785947 or https://www.thingiverse.com/thing:3982923 or https://www.thingiverse.com/thing:4156764 There's no reason for me to reinvent the wheel. Then, the most difficult thing would be determining the length of new feed tube to cut. --Bed Leveling Knobs-- I recommend these bed leveling knobs: https://www.thingiverse.com/thing:2603493 --XBelt Guide-- The spacer that acts as a guide to assist in aligning the xbelt is available at: https://www.thingiverse.com/thing:2758518 --Notes-- This setup uses #8 threaded rod or long bolts. At least 30% infill is recommended, with 100% on the duct. No supports are needed except for the direct drive mount. I always raft the parts. After the direct drive upgrade, you can reduce retraction significantly or entirely if you don't mind some stringing.
