Ender-3 Direct Drive (Stock fan house) with BLTouch FSR and Cable Guide

thingiverse

This is an updated version plus Add-on for the Ender-3 Direct Drive Stock fan housing with BL Touch, https://www.thingiverse.com/thing:3443609 by Kralexwa. I added holes and space for attaching the Filament Sensor as described here. In addition, I designed a cable guide to be mounted onto the E-Plate roller spacers. To assemble, remove the two roller screws of the E-Plate and insert the roller spacers into the cable guide. Then, put the extruder motor holder back together with the E-Plate and rollers. Before putting in the extruder motor, make sure you inserted the two M3 nuts for the Filament Runout Sensor into the extruder holder. The available Filament Runout Sensors are all too high and may run into the filament spool if the Z-Axis goes high enough. This Filament Runout Sensor only adds 13mm height to the Extruder top. Solder a 2 Pin JST-XH connector onto the switch as shown in the image. Soldering the cable directly onto the switch is also possible, but not that nice. To successfully integrate the Filament Runout Sensor into your printer firmware, please refer to the many instructions available on the internet. There are too many possibilities depending on the controller board and Creality printer you have. Material needed for the Filament Sensor: - 2 x M2 x 12 - 2 x M2 Nut - 2 x M3 x 6 - 2 x M3 Nut - 1 x Steel Ball 7 mm - 1 x JST-XH 2 Pin connector - 1 x Micro Switch 13mm x 6 mm, e.g "Hartmann MDB1 05C01C01A": https://www.conrad.com/p/hartmann-microswitch-microhart-125-v-ac-3-a-1-x-onon-momentary-1-pcs-704713 or "KW10-Z0P" (please google it for a local source). It's the same switch you have in the Ender-3 as end stop switches, just without lever. If you only find this type with lever, you can also use it but have to remove the lever.
