PoPprint All-Metal l Heatbreak Throat for V6 RepRap 3D Printer Hotend 1.75mm (Pack of 5pcs) (All Metal)

All metal e3d throats, they fit and the filament run through them, not much else you can say really

The heater-block end has a large chamfer which helps cause clogs.The bore is ~1.8mm as opposed to E3D's ~2.2mm bore. This makes it easier for filament with varying width to jam.The length is also about 0.1mm shorter than a genuine E3D. Which isn't an issue unless you use dual extruders and calibration is a pain.I'm attaching a photo of two simple cone test prints. These were printed from the exact same Gcode with the exact same perameters except the one on the left was with a genuine E3D V6 and the one on the right was with this product.If you are going all-metal throat, I suggest getting the genuine item even if the rest of your assembly is clone.
