Bulldog Extruder on Ender 3

thingiverse

I'm moving from the factory extruder to the bulldog, but I quickly realize that there's no way to support the hotend and fan cables properly. That's where this new device comes in - it'll take care of everything. It's designed to fit snugly into place using the 3mm and 5mm mounting holes, so make sure you're using 8mm long screws for a secure hold. The coupler is cleverly designed with a little extra room for easy access. You can slide in and out without any hassle at all. I've taken some liberties with the design to get it just right - the posted model is actually 1mm shorter than usual, which helps it line up perfectly with the edge of the extruder.
