Bullseye Strain Relief Ender 3 Pro

thingiverse

I created this remix because it heavily drew inspiration from that original bowden holder, but it was essentially built from scratch. The original design didn't match up with my frame at all, so I had to obtain the Creality technical drawing and rebuild it according to proper specs. Then, I pushed the wire holder out to one side since the bullseye base has the heater and thermistor wiring running outside the housing instead of inside like the stock version. Trying to connect to the bowden from the outside introduces a hinge point that rocks as the X-axis moves back and forth, which kept wearing out my Picoblade connectors on the bl-touch. This is meant for use with the [bullseye base](https://www.thingiverse.com/thing:3244704) that has the cable guide removed. It's especially useful with a right side mounted bl-touch to keep everything perfectly still because properly crimping a 5 pin Picoblade on 28ga silicone ribbon is frustratingly difficult, and I believe cable chains between the extruder and hot-end are unnecessary if not counterproductive. Zip tie slots are 3mm tall and should accept most, if not all, 4inch zip ties. Update: V4 shifted the bowden holder side about 1.5mm to the left to get it true to center with the mounting points for the heat-break per Creality's blueprints for the carriage.
