About this 3D model

This is i3ext by sgraber, which I modified for E3D v5 hot end and 1.75 mm filament. The normal J-Head mount does not work perfectly with E3D because the mount geometry is a little bit different. This one fits perfect. Equipped with involute gear profile to provide a constant gear ratio during movement of the extruder gears. Straight cut gears do not provide such a feature. BOM: - Nema 17 motor - E3D v5 hot end - 2x 625ZZ - 1x 608ZZ - Silicone hose or springs - About 50-60 mm long M5 rod - About 20 mm long M8 rod - M3 nuts and bolts - MK7 filament drive gear - Probably forgot something
