--Simplicity 5015 cooling fan mounts and duct-- This is an efficent, effective, quieter, simple setup that allows quick and easy access to maintain the extruder. You may wish to run the parts cooler slower as its a stronger fan. --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 repin 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. Just 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. Such as: 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 No reason for me to reinvent the wheel. Then most difficult thing would then be determining the length of new feed tube to cut. --Bed Leveling Knobs-- I recomend 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: https://www.thingiverse.com/thing:2758518 --Notes-- uses #8 threaded rod or long bolts. At least 30% infil is recomended. 100% on the duct. No supports needed except on the direct drive mount. I do raft the parts though. After the direct drive upgrade you can reduce retraction signifigantly or entirely if you don't mind some stringing.
