Ender 3 Pro Direct Drive Extruder

Version 1 18/10/21:Designed purely for use with an Ender 3 that uses a linear rail for the X-carriage assembly and sensorless homing. This design has not been tested with limit switches!Designed to be used with a standard Creality Ender 3 style hot end, I have combined my favourite part cooling system and my own modified extruder mount to feed TPU and other materials more consistently.Assembly requires insertion of Capricorn tubing into hot-end before inserting into extruder, cut the Capricorn tubing to a nice sharp angle to reduce the chance of filament binding during extrusion as seen in this video: https://www.youtube.com/watch?v=CJ0h3_vNpnoPlease note that assembling parts requires thermally inserting brass threaded inserts! 3D print settings may alter the accuracy / tightness of fittings and minor post processing may be necessary based on your printer.The original part cooling and mounting setup and additional fittings list can be found here:https://www.thingiverse.com/thing:4725293The original BL-Touch mount can be found here:https://www.thingiverse.com/thing:4141103Original fan cover can be found here:https://www.thingiverse.com/thing:1720087
