About this 3D model

This is my MK8 one piece heavy duty Extruder for 3mm and 1.75mm filament. Uses standard Nema 17, 608 Bearing, M8 bolt and nut, M3 screws and nuts, and two small springs for M3 screws. Some bridging may be required. I designed 4 different versions for built in j-head mount and 90 degree mounting. Also included is my FreeCAD design file. Hope you like it.
