Aluminum Alloy M4 Kossel Fisheye Effector 4mm Hammock Hanging Station For 3D Printer Extruder Part

Looks pretty much like the picture. Maybe a bit less refined. It's cast aluminum. Dimensions seem perfect. All three different E3D hotends fit easily with almost no play. I do t think I'd want it to be any more snug. The tapped screw-holes fit the brace which keeps the hotend in. I think my only complaint is that this is sold without that brace. It seems to me that everyone buying this will also need the brace -- it would make sense to sell them together as a matched set to ensure compatibility.

this one works well, can even be used with 3mm screws, but need counter nuts for that to work rigidly.
