Ender 3 (All Models) - Direct drive and Fan Ducts, BL Touch Compatible

thingiverse

This project is a conglomeraion of several models and features i wanted in one compact package, namely a direct drive mount and a fan system similar to the Petsfang Bullseye duct. All of the printable parts are either original or heavily modified and they all work together in a compact and cohesive unit. The models used will be listed at the bottom of this section. _______________________________ Tools needed: ================= Super glue M3 tap M4 tap soldering iron/wire stripper to splice the fan cables. __________________________ Bill of materials: ======== Blower fans: https://www.amazon.com/gp/product/B071WMHNG5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If you <b>ARE NOT</b> using the intake cowls you will need: 2x M4x20 2x M4x25 one of each for each blower fan, see assembly for details. If you <B>ARE</b> using the intake cowls you will need 2x M4x30 2x M4x25 3x M3x25 If you are using a <b>BL Touch</b> sensor you will need: 2x M3x8 2x M3 hex nuts 2x M4 flat head Plus the mounting hardware you'd normally use to attach a BLTouch. The frame mounts to the X-axis carriage via the two screws that hold the little metal box on the stock printer. The extruder is held on by the stock fasteners. Please see the assembly file for orientation. You will need a length of PTFE tubing to bridge the extruder and the hot end, I just eyeballed the length. _____________________________ Reference models used: ====================== Bltouch adjustable mount: https://www.thingiverse.com/thing:2122894 BLTouch Model: https://grabcad.com/library/bltouch-v3-1-2 BLTouch Documentation: https://locxess.de/3d/BLTouch_Anleitung_englisch.pdf Bullseye fan duct system: https://www.thingiverse.com/thing:2759439 Ender 3 cad model: https://grabcad.com/library/creality-ender-3-pro-1
