I have an E3D Titan clone (TH3D Tough) Extruder I'm installing on my Ender 5 and wanted a way to keep my filament dust-free and dry. The TH3D Tough extruder only allowed bare filament to feed through the top of their tough extruder arm so I remixed mihatomi's E3D Titan design in Tinkercad to fit my needs. This allows better fitment of the extruder arm bearing (10mm x 4mm thick) and fitment onto the TH3D supplied pancake stepper motor that the original design did not fit, as well as add a threaded adapter for a pass-through capricorn PTFE tube using a PC4-M10 fitting.
Leave orientation as-is, apply 1 support blocker to inside upper center of bearing recess. Bridging will be fine, supports will just muddy it up if you're even able to fish them all out.
I used 100% infill, 0.2 or 0.12 layer heights, supports everywhere, 0 support walls, and 7% support infill. Removes easily and cleanly. Use brim to promote adhesion and avoid accidentally knocking over print.
