Ender 3 Direct Drive Mount

I designed this direct drive mounting bracket to use the stock extruder and mount it on the x carriage so I could print TPU without any purchased modifications. I did use a short length of Capricorn tubing between the extruder and hot end, the stock bowden tube should work just fine. I just wanted to be able to go back to stock if I wasn't happy with the experiment.

So far, it's worked flawlessly. I've printed TPU, PLA, PLA+, and PETG without issue. Retraction settings need to be adjusted a bit depending on material and what you're printing, but that's all I've done and I'm getting great quality prints.

I made it a bit more print-friendly, fewer supports, and open sided with a pin so that you can lay the wires into it and cap it, instead of feeding them through a hole. This way you don't need to disconnect the wires to in
