Petsfang Bowden Direct with Bondtech BMG for CR10/S/4, Ender3 and Tevo Tornado
by dpetsel

I think you can use the normal petfang or bulleye with this mod

Hi, for that bmg you cam download tbis one:


Thank you again for providing a mount that works with the original sized BMG clone. I printed it out this evening and it looks much better than the one for the mini-BMG. If you don't mind I have a couple observations. First, I commend the inclusion of the bracket for wire management. I think strain relief for the wires is useful and will make the setup more reliable. Unfortunately, my extruder only has three mounting holes and the strain relief covers one of them. I'm thinking I can drill a hole through the wire relief to get access to the screw but that seems like a bit of a hack. Second, on my printer the outlet for the extruder is a little bit out of the alignment with the hot end. I've tried moving things around but it's still a bit off. When looking at the printer, it seems like the extruder needs to move about 2 mm to the left. It's not much and I suspect the setup will still work, it's just not quite aligned and I thought you would appreciate my feedback.
I really like your mount. It's great that it works with the existing fan box and doesn't get in the way if I want to mount a BLTOUCH. I also like the location of the stepper motor because I think it will cause less of a moment on the guide wheels which should improve print quality. Thanks for your hard work.

Thank you for your observatios but they are for the bmg or the bmg mini mount?

Thank you, I'll give it a try.
